==History of the infinitesimal==
The notion of infinitely small quantities was discussed by the [[Eleatic School]]. The [[Greek mathematics|Greek]] mathematician [[Archimedes]] (c.287 BC–c.212 BC), in ''[[The Method of Mechanical Theorems]]'', was the first to propose a logically rigorous definition of infinitesimals.<ref>Archimedes, ''The Method of Mechanical Theorems''; see [[Archimedes Palimpsest]]</ref> His [[Archimedean property]] defines a number ''x'' as infinite if it satisfies the conditions |x| > 1, |x| > 1 + 1, |x| > 1 + 1 + 1, ..., and infinitesimal if x≠0 and a similar set of conditions holds for 1/x and the reciprocals of the positive integers. A number system is said to be Archimedean if it contains no infinite or infinitesimal members.

The use of infinitesimals was attacked as incorrect by [[George Berkeley|Bishop Berkeley]] in his work ''[[The Analyst]]''.<ref>George Berkeley, ''The Analyst; or a discourse addressed to an infidel mathematician''</ref>  Mathematicians, scientists, and engineers continued to use infinitesimals to produce correct results. In the second half of the nineteenth century, the calculus was reformulated by [[Augustin-Louis Cauchy]], [[Bernard Bolzano]], [[Karl Weierstrass]], [[Georg Cantor|Cantor]], [[Dedekind]], and others using the [[(ε, δ)-definition of limit]] and [[set theory]].
 
While the followers of Cantor, Dedekind, and Weierstrass sought to rid infinitesimals from analysis and their philosophical allies like [[Bertrand Russell]] and [[Rudolf Carnap]] declared infinitesimals to be "pseudoconcepts", [[Hermann Cohen]] and his [[Marburg school]] of [[neo-Kantianism]] sought to develop a working logic of infinitesimals.<ref>[[Thomas Mormann]]; [[Mikhail Katz]]. Infinitesimals as an issue of neo-Kantian philosophy of science.

See  http://www.jstor.org/stable/10.1086/671348 and http://arxiv.org/abs/1304.1027 </ref> The mathematical study of systems containing infinitesimals continued through the work of [[Tullio Levi-Civita|Levi-Civita]], [[Paul du Bois-Reymond]], and others, throughout the late nineteenth and the twentieth centuries, as documented by [[Philip Ehrlich]] (2006).  In the 20th century, it was found that infinitesimals could serve as a basis for calculus and analysis; see [[hyperreal number]].
 
==First-order properties==
 
{{Expert-subject|Mathematics|section|talk=First-order properties|reason=exposition is muddled}}
 
In extending the real numbers to include infinite and infinitesimal quantities, one typically wishes to be as conservative as possible by not changing any of their elementary properties. This guarantees that as many familiar results as possible will still be available. Typically ''elementary'' means that there is no [[quantifier|quantification]] over [[set (mathematics)|sets]], but only over elements. This limitation allows statements of the form "for any number x..." For example, the axiom that states "for any number&nbsp;''x'', ''x''&nbsp;+&nbsp;0&nbsp;=&nbsp;''x''" would still apply. The same is true for quantification over several numbers, e.g., "for any numbers&nbsp;''x'' and ''y'', ''xy''&nbsp;=&nbsp;''yx''."  However, statements of the form "for any ''set''&nbsp;''S''&nbsp;of numbers&nbsp;..." may not carry over. Logic with this limitation on quantification is referred to as [[first-order logic]].
 
It superficially seems clear that the resulting extended number system cannot agree with the reals on all properties that can be expressed by quantification over sets, because the goal is to construct a nonarchimedean system, and the Archimedean principle can be expressed by quantification over sets, but this is incorrect. It is trivial to conservatively extend any theory including reals, including set theory, to include infinitesimals, just by adding a countably infinite list of axioms that assert that a number is smaller than 1/2, 1/3, 1/4 and so on. Similarly, the [[Complete metric space|completeness]] property cannot be expected to carry over, because the reals are the unique complete ordered field up to isomorphism. This is also wrong, at least as a formal statement, since it presuming some underlying model of set theory.
 
We can distinguish three levels at which a nonarchimedean number system could have first-order properties compatible with those of the reals:
 
# An [[ordered field]] obeys all the usual axioms of the real number system that can be stated in first-order logic. For example, the [[commutativity]] axiom ''x''&nbsp;+&nbsp;''y''&nbsp;=&nbsp;''y''&nbsp;+&nbsp;''x'' holds.
# A [[real closed field]] has all the first-order properties of the real number system, regardless of whether they are usually taken as axiomatic, for statements involving the basic ordered-field relations +,&nbsp;×, and&nbsp;≤. This is a stronger condition than obeying the ordered-field axioms.  More specifically, one includes additional first-order properties, such as the existence of a root for every odd-degree polynomial. For example, every number must have a [[cube root]].
# The system could have all the first-order properties of the real number system for statements involving ''any'' relations (regardless of whether those relations can be expressed using&nbsp;+,&nbsp;×, and&nbsp;≤). For example, there would have to be a [[sine]] function that is well defined for infinite inputs; the same is true for every real function.
 
Systems in category 1, at the weak end of the spectrum, are relatively easy to construct, but do not allow a full treatment of classical analysis using infinitesimals in the spirit of Newton and Leibniz. For example, the [[transcendental functions]] are defined in terms of infinite limiting processes, and therefore there is typically no way to define them in first-order logic. Increasing the analytic strength of the system by passing to categories&nbsp;2 and&nbsp;3, we find that the flavor of the treatment tends to become less constructive, and it becomes more difficult to say anything concrete about the hierarchical structure of infinities and infinitesimals.
 
==Number systems that include infinitesimals==
===Formal series===
====Laurent series====
An example from category 1 above is the field of [[Laurent series]] with a finite number of negative-power terms. For example, the Laurent series consisting only of the constant term 1 is identified with the real number&nbsp;1, and the series with only the linear term&nbsp;''x'' is thought of as the simplest infinitesimal, from which the other infinitesimals are constructed. Dictionary ordering is used, which is equivalent to considering higher powers of&nbsp;''x'' as negligible compared to lower powers. [[David O. Tall]]<ref>{{cite web|url=http://www.jonhoyle.com/MAAseaway/Infinitesimals.html |title=Infinitesimals in Modern Mathematics |publisher=Jonhoyle.com |date= |accessdate=2011-03-11}}</ref> refers to this system as the super-reals, not to be confused with the [[superreal number]] system of Dales and Woodin. Since a Taylor series evaluated with a Laurent series as its argument is still a Laurent series, the system can be used to do calculus on transcendental functions if they are analytic. These infinitesimals have different first-order properties than the reals because, for example, the basic infinitesimal&nbsp;''x'' does not have a square root.
 
====The Levi-Civita field====
The [[Levi-Civita field]] is similar to the Laurent series, but is algebraically closed. For example, the basic infinitesimal x has a square root. This field is rich enough to allow a significant amount of analysis to be done, but its elements can still be represented on a computer in the same sense that real numbers can be represented in floating point. <ref>Khodr Shamseddine, "Analysis on the Levi-Civia Field: A Brief Overview," http://www.uwec.edu/surepam/media/RS-Overview.pdf</ref>
 
====Transseries====
The field of [[transseries]] is larger than the Levi-Civita field.<ref>G. A. Edgar, "Transseries for Beginners," http://www.math.ohio-state.edu/~edgar/preprints/trans_begin/</ref> An example of a transseries is:
 
:<math>e^\sqrt{\ln\ln x}+\ln\ln x+\sum_{j=0}^\infty e^x x^{-j},</math>
 
where for purposes of ordering ''x'' is considered to be infinite.
 
===Surreal numbers===
Conway's [[surreal numbers]] fall into category 2. They are a system that was designed to be as rich as possible in different sizes of numbers, but not necessarily for convenience in doing analysis. Certain transcendental functions can be carried over to the surreals, including logarithms and exponentials, but most, e.g., the sine function, cannot. The existence of any particular surreal number, even one that has a direct counterpart in the reals, is not known a priori, and must be proved.
 
===Hyperreals===
{{Main|Hyperreal number}}
The most widespread technique for handling infinitesimals is the hyperreals, developed by [[Abraham Robinson]] in the 1960s. They fall into category 3 above, having been designed that way in order to allow all of classical analysis to be carried over from the reals. This property of being able to carry over all relations in a natural way is known as the [[transfer principle]], proved by [[Jerzy Łoś]] in 1955.  For example, the transcendental function sin has a natural counterpart *sin that takes a hyperreal input and gives a hyperreal output, and similarly the set of natural numbers <math>\mathbb{N}</math> has a natural counterpart <math>^*\mathbb{N}</math>, which contains both finite and infinite integers. A proposition such as <math>\forall n \in \mathbb{N}, \sin n\pi=0</math> carries over to the hyperreals as <math>\forall n \in {}^*\mathbb{N}, {}^*\!\!\sin n\pi=0</math> .
 
===Superreals===
The [[superreal number]] system of Dales and Woodin is a generalization of the hyperreals. It is different from the super-real system defined by [[David O. Tall|David Tall]].
 
===Smooth infinitesimal analysis ===
{{Main|Smooth infinitesimal analysis}}
[[Synthetic differential geometry]] or [[smooth infinitesimal analysis]] have roots in [[category theory]]. This approach departs from the classical logic used in conventional mathematics by denying the general applicability of the [[law of excluded middle]] &mdash; i.e., ''not'' (''a'' ≠ ''b'')  does not have to mean ''a'' = ''b''. A ''nilsquare'' or ''[[nilpotent]]'' infinitesimal can then be defined. This is a number ''x'' where ''x''<sup>2</sup> = 0 is true, but ''x'' = 0 need not be true at the same time. Since the background logic is [[intuitionistic logic]], it is not immediately clear how to classify this system with regard to classes 1, 2, and 3. Intuitionistic analogues of these classes would have to be developed first.
 
==Infinitesimal delta functions==
[[Cauchy]] used an infinitesimal <math>\alpha</math> to write down a unit impulse, infinitely tall and narrow Dirac-type delta function <math>\delta_\alpha</math> satisfying <math>\int F(x)\delta_\alpha(x) = F(0)</math> in a number of articles in 1827, see Laugwitz (1989).  Cauchy defined an infinitesimal in 1821 (Cours d'Analyse) in terms of a sequence tending to zero.  Namely, such a null sequence becomes an infinitesimal in Cauchy's and [[Lazare Carnot]]'s terminology.
 
Modern set-theoretic approaches allow one to define infinitesimals via the [[ultrapower]] construction, where a null sequence becomes an infinitesimal in the sense of an equivalence class modulo a relation defined in terms of a suitable [[ultrafilter]]. The article by Yamashita (2007) contains a bibliography on modern [[Dirac delta function]]s in the context of an infinitesimal-enriched continuum provided by the [[hyperreal number|hyperreals]].
 
==Logical properties==
The method of constructing infinitesimals of the kind used in nonstandard analysis depends on the [[Model theory|model]] and which collection of [[axiom]]s are used. We consider here systems where infinitesimals can be shown to exist.
 
In 1936 [[Maltsev]] proved the [[compactness theorem]]. This theorem is fundamental for the existence of infinitesimals as it proves that it is possible to formalise them. A consequence of this theorem is that if there is a number system in which it is true that for any positive integer ''n'' there is a positive number ''x'' such that 0&nbsp;<&nbsp;''x''&nbsp;<&nbsp;1/''n'', then there exists an extension of that number system in which it is true that there exists a positive number ''x'' such that for any positive integer ''n'' we have 0&nbsp;<&nbsp;''x''&nbsp;<&nbsp;1/''n''. The possibility to switch  "for any" and "there exists" is crucial. The first statement is true in the real numbers as given in [[ZFC]] [[set theory]] : for any positive integer ''n'' it is possible to find a real number between 1/''n'' and zero, but this real number will depend on ''n''. Here, one chooses ''n'' first, then one finds the corresponding ''x''. In the second expression, the statement says that there is an  ''x'' (at least one), chosen first, which is between 0 and 1/''n'' for any ''n''. In this case ''x'' is infinitesimal. This is not true in the real numbers ('''R''') given by ZFC. Nonetheless, the theorem proves that there is a model (a number system) in which this will be true. The question is: what is this model? What are its properties? Is there only one such model?
 
There are in fact many ways to construct such a [[dimension|one-dimensional]] [[linear order|linearly ordered]] set of numbers, but fundamentally, there are two different approaches:
 
: 1) Extend the number system so that it contains more numbers than the real numbers.
 
: 2) Extend the axioms (or extend the language) so that the distinction between the infinitesimals and non-infinitesimals can be made in the real numbers themselves.
 
In 1960, [[Abraham Robinson]] provided an answer following the first approach. The extended set is called the [[Hyperreal number|hyperreal]]s and contains numbers less in absolute value than any positive real number. The method may be considered relatively complex but it does prove that infinitesimals exist in the universe of ZFC set theory. The real numbers are called standard numbers and the new non-real hyperreals are called [[Non-standard analysis|nonstandard]].
 
In 1977 [[Edward Nelson]] provided an answer following the second approach. The extended axioms are IST, which stands either for [[Internal set theory|Internal Set Theory]] or for the initials of the three extra axioms: Idealization, Standardization, Transfer. In this system we consider that the language is extended in such a way that we can express facts about infinitesimals. The real numbers are either standard or nonstandard. An infinitesimal is a nonstandard real number which is less, in absolute value, than any positive standard real number.
 
In 2006 [http://math.sci.ccny.cuny.edu/people?name=Karel_Hrbacek Karel Hrbacek] developed an extension of Nelson's approach in which the real numbers are stratified in (infinitely) many levels; i.e., in the coarsest level there are no infinitesimals nor unlimited numbers. Infinitesimals are in a finer level and there are also infinitesimals with respect to this new level and so on.
==Infinitesimals in teaching==
Calculus textbooks based on infinitesimals include the classic ''[[Calculus Made Easy]]'' by [[Silvanus P. Thompson]], and bearing the motto "What one fool can do another can".<ref>Available online at
http://www.gutenberg.org/ebooks/33283</ref> Pioneering works based on [[Abraham Robinson]]'s infinitesimals include texts by [[Stroyan]] (dating from 1972) and [[Howard Jerome Keisler]] ([[Elementary Calculus: An Infinitesimal Approach]]). Students easily relate to the intuitive notion of an infinitesimal difference 1-"[[0.999...]]", where  "0.999..." differs from its standard meaning as the real number 1, and is reinterpreted as an infinite terminating extended decimal that is strictly less than 1.<ref>*{{Cite journal |last=Ely |first=Robert |year=2010 |title=Nonstandard student conceptions about infinitesimals |journal=[[Journal for Research in Mathematics Education]] |volume=41 |issue=2 |pages=117–146}}</ref><ref>http://www.math.umt.edu/tmme/vol7no1/TMME_vol7no1_2010_article1_pp.3_30.pdf</ref>

Infinitesimals have been used to express the idea of objects so small that there is no way to see them or to measure them. The insight with exploiting infinitesimals was that objects could still retain certain specific properties, such as angle or slope, even though these objects were quantitatively small.[1] The word infinitesimal comes from a 17th-century Modern Latin coinage infinitesimus, which originally referred to the "infinite-th" item in a sequence. It was originally introduced around 1670 by either Nicolaus Mercator or Gottfried Wilhelm Leibniz,[2] and are a basic building block of infinitesimal calculus.

In common speech, an infinitesimal object is an object which is smaller than any feasible measurement, but not zero in size; or, so small that it cannot be distinguished from zero by any available means. Hence, when used as an adjective, "infinitesimal" means "extremely small". In order to give it a meaning it usually has to be compared to another infinitesimal object in the same context (as in a derivative). Infinitely many infinitesimals are summed to produce an integral.

Archimedes used what eventually came to be known as the Method of indivisibles in his work The Method of Mechanical Theorems to find areas of regions and volumes of solids.[3] In his formal published treatises, Archimedes solved the same problem using the Method of Exhaustion. The 15th century saw the work of Nicholas of Cusa, further developed in the 17th century by Johannes Kepler, in particular calculation of area of a circle by representing the latter as an infinite-sided polygon. Simon Stevin's work on decimal representation of all numbers in the 16th century prepared the ground for the real continuum. Bonaventura Cavalieri's method of indivisibles led to an extension of the results of the classical authors. The method of indivisibles related to geometrical figures as being composed of entities of codimension 1. John Wallis's infinitesimals differed from indivisibles in that he would decompose geometrical figures into infinitely thin building blocks of the same dimension as the figure, preparing the ground for general methods of the integral calculus. He exploited an infinitesimal denoted in area calculations.

The use of infinitesimals by Leibniz relied upon heuristic principles, such as the Law of Continuity: what succeeds for the finite numbers succeeds also for the infinite numbers and vice versa; and the Transcendental Law of Homogeneity that specifies procedures for replacing expressions involving inassignable quantities, by expressions involving only assignable ones. The 18th century saw routine use of infinitesimals by mathematicians such as Leonhard Euler and Joseph-Louis Lagrange. Augustin-Louis Cauchy exploited infinitesimals both in defining continuity in his Cours d'Analyse, and in defining an early form of a Dirac delta function. As Cantor and Dedekind were developing more abstract versions of Stevin's continuum, Paul du Bois-Reymond wrote a series of papers on infinitesimal-enriched continua based on growth rates of functions. Du Bois-Reymond's work inspired both Émile Borel and Thoralf Skolem. Borel explicitly linked du Bois-Reymond's work to Cauchy's work on rates of growth of infinitesimals. Skolem developed the first non-standard models of arithmetic in 1934. A mathematical implementation of both the law of continuity and infinitesimals was achieved by Abraham Robinson in 1961, who developed non-standard analysis based on earlier work by Edwin Hewitt in 1948 and Jerzy Łoś in 1955. The hyperreals implement an infinitesimal-enriched continuum and the transfer principle implements Leibniz's law of continuity. The standard part function implements Fermat's adequality.

History of the infinitesimal

The notion of infinitely small quantities was discussed by the Eleatic School. The Greek mathematician Archimedes (c.287 BC–c.212 BC), in The Method of Mechanical Theorems, was the first to propose a logically rigorous definition of infinitesimals.[4] His Archimedean property defines a number x as infinite if it satisfies the conditions |x| > 1, |x| > 1 + 1, |x| > 1 + 1 + 1, ..., and infinitesimal if x≠0 and a similar set of conditions holds for 1/x and the reciprocals of the positive integers. A number system is said to be Archimedean if it contains no infinite or infinitesimal members.

The Indian mathematician Bhāskara II (1114–1185)[5] described a geometric technique for expressing the change in in terms of times a change in . Prior to the invention of calculus mathematicians were able to calculate tangent lines by the method Pierre de Fermat's method of adequality and René Descartes' method of normals. There is debate among scholars as to whether the method was infinitesimal or algebraic in nature. When Newton and Leibniz invented the calculus, they made use of infinitesimals. The use of infinitesimals was attacked as incorrect by Bishop Berkeley in his work The Analyst.[6] Mathematicians, scientists, and engineers continued to use infinitesimals to produce correct results. In the second half of the nineteenth century, the calculus was reformulated by Augustin-Louis Cauchy, Bernard Bolzano, Karl Weierstrass, Cantor, Dedekind, and others using the (ε, δ)-definition of limit and set theory.

While the followers of Cantor, Dedekind, and Weierstrass sought to rid infinitesimals from analysis and their philosophical allies like Bertrand Russell and Rudolf Carnap declared infinitesimals to be "pseudoconcepts", Hermann Cohen and his Marburg school of neo-Kantianism sought to develop a working logic of infinitesimals.[7] The mathematical study of systems containing infinitesimals continued through the work of Levi-Civita, Paul du Bois-Reymond, and others, throughout the late nineteenth and the twentieth centuries, as documented by Philip Ehrlich (2006). In the 20th century, it was found that infinitesimals could serve as a basis for calculus and analysis; see hyperreal number.

First-order properties

Template:Expert-subject

In extending the real numbers to include infinite and infinitesimal quantities, one typically wishes to be as conservative as possible by not changing any of their elementary properties. This guarantees that as many familiar results as possible will still be available. Typically elementary means that there is no quantification over sets, but only over elements. This limitation allows statements of the form "for any number x..." For example, the axiom that states "for any number x, x + 0 = x" would still apply. The same is true for quantification over several numbers, e.g., "for any numbers x and y, xy = yx." However, statements of the form "for any set S of numbers ..." may not carry over. Logic with this limitation on quantification is referred to as first-order logic.

It superficially seems clear that the resulting extended number system cannot agree with the reals on all properties that can be expressed by quantification over sets, because the goal is to construct a nonarchimedean system, and the Archimedean principle can be expressed by quantification over sets, but this is incorrect. It is trivial to conservatively extend any theory including reals, including set theory, to include infinitesimals, just by adding a countably infinite list of axioms that assert that a number is smaller than 1/2, 1/3, 1/4 and so on. Similarly, the completeness property cannot be expected to carry over, because the reals are the unique complete ordered field up to isomorphism. This is also wrong, at least as a formal statement, since it presuming some underlying model of set theory.

We can distinguish three levels at which a nonarchimedean number system could have first-order properties compatible with those of the reals:

  1. An ordered field obeys all the usual axioms of the real number system that can be stated in first-order logic. For example, the commutativity axiom x + y = y + x holds.
  2. A real closed field has all the first-order properties of the real number system, regardless of whether they are usually taken as axiomatic, for statements involving the basic ordered-field relations +, ×, and ≤. This is a stronger condition than obeying the ordered-field axioms. More specifically, one includes additional first-order properties, such as the existence of a root for every odd-degree polynomial. For example, every number must have a cube root.
  3. The system could have all the first-order properties of the real number system for statements involving any relations (regardless of whether those relations can be expressed using +, ×, and ≤). For example, there would have to be a sine function that is well defined for infinite inputs; the same is true for every real function.

Systems in category 1, at the weak end of the spectrum, are relatively easy to construct, but do not allow a full treatment of classical analysis using infinitesimals in the spirit of Newton and Leibniz. For example, the transcendental functions are defined in terms of infinite limiting processes, and therefore there is typically no way to define them in first-order logic. Increasing the analytic strength of the system by passing to categories 2 and 3, we find that the flavor of the treatment tends to become less constructive, and it becomes more difficult to say anything concrete about the hierarchical structure of infinities and infinitesimals.

Number systems that include infinitesimals

Formal series

Laurent series

An example from category 1 above is the field of Laurent series with a finite number of negative-power terms. For example, the Laurent series consisting only of the constant term 1 is identified with the real number 1, and the series with only the linear term x is thought of as the simplest infinitesimal, from which the other infinitesimals are constructed. Dictionary ordering is used, which is equivalent to considering higher powers of x as negligible compared to lower powers. David O. Tall[8] refers to this system as the super-reals, not to be confused with the superreal number system of Dales and Woodin. Since a Taylor series evaluated with a Laurent series as its argument is still a Laurent series, the system can be used to do calculus on transcendental functions if they are analytic. These infinitesimals have different first-order properties than the reals because, for example, the basic infinitesimal x does not have a square root.

The Levi-Civita field

The Levi-Civita field is similar to the Laurent series, but is algebraically closed. For example, the basic infinitesimal x has a square root. This field is rich enough to allow a significant amount of analysis to be done, but its elements can still be represented on a computer in the same sense that real numbers can be represented in floating point. [9]

Transseries

The field of transseries is larger than the Levi-Civita field.[10] An example of a transseries is:

where for purposes of ordering x is considered to be infinite.

Surreal numbers

Conway's surreal numbers fall into category 2. They are a system that was designed to be as rich as possible in different sizes of numbers, but not necessarily for convenience in doing analysis. Certain transcendental functions can be carried over to the surreals, including logarithms and exponentials, but most, e.g., the sine function, cannot. The existence of any particular surreal number, even one that has a direct counterpart in the reals, is not known a priori, and must be proved.

Hyperreals

Mining Engineer (Excluding Oil ) Truman from Alma, loves to spend time knotting, largest property developers in singapore developers in singapore and stamp collecting. Recently had a family visit to Urnes Stave Church. The most widespread technique for handling infinitesimals is the hyperreals, developed by Abraham Robinson in the 1960s. They fall into category 3 above, having been designed that way in order to allow all of classical analysis to be carried over from the reals. This property of being able to carry over all relations in a natural way is known as the transfer principle, proved by Jerzy Łoś in 1955. For example, the transcendental function sin has a natural counterpart *sin that takes a hyperreal input and gives a hyperreal output, and similarly the set of natural numbers has a natural counterpart , which contains both finite and infinite integers. A proposition such as carries over to the hyperreals as .

Superreals

The superreal number system of Dales and Woodin is a generalization of the hyperreals. It is different from the super-real system defined by David Tall.

Smooth infinitesimal analysis

Mining Engineer (Excluding Oil ) Truman from Alma, loves to spend time knotting, largest property developers in singapore developers in singapore and stamp collecting. Recently had a family visit to Urnes Stave Church. Synthetic differential geometry or smooth infinitesimal analysis have roots in category theory. This approach departs from the classical logic used in conventional mathematics by denying the general applicability of the law of excluded middle — i.e., not (ab) does not have to mean a = b. A nilsquare or nilpotent infinitesimal can then be defined. This is a number x where x2 = 0 is true, but x = 0 need not be true at the same time. Since the background logic is intuitionistic logic, it is not immediately clear how to classify this system with regard to classes 1, 2, and 3. Intuitionistic analogues of these classes would have to be developed first.

Infinitesimal delta functions

Cauchy used an infinitesimal to write down a unit impulse, infinitely tall and narrow Dirac-type delta function satisfying in a number of articles in 1827, see Laugwitz (1989). Cauchy defined an infinitesimal in 1821 (Cours d'Analyse) in terms of a sequence tending to zero. Namely, such a null sequence becomes an infinitesimal in Cauchy's and Lazare Carnot's terminology.

Modern set-theoretic approaches allow one to define infinitesimals via the ultrapower construction, where a null sequence becomes an infinitesimal in the sense of an equivalence class modulo a relation defined in terms of a suitable ultrafilter. The article by Yamashita (2007) contains a bibliography on modern Dirac delta functions in the context of an infinitesimal-enriched continuum provided by the hyperreals.

Logical properties

The method of constructing infinitesimals of the kind used in nonstandard analysis depends on the model and which collection of axioms are used. We consider here systems where infinitesimals can be shown to exist.

In 1936 Maltsev proved the compactness theorem. This theorem is fundamental for the existence of infinitesimals as it proves that it is possible to formalise them. A consequence of this theorem is that if there is a number system in which it is true that for any positive integer n there is a positive number x such that 0 < x < 1/n, then there exists an extension of that number system in which it is true that there exists a positive number x such that for any positive integer n we have 0 < x < 1/n. The possibility to switch "for any" and "there exists" is crucial. The first statement is true in the real numbers as given in ZFC set theory : for any positive integer n it is possible to find a real number between 1/n and zero, but this real number will depend on n. Here, one chooses n first, then one finds the corresponding x. In the second expression, the statement says that there is an x (at least one), chosen first, which is between 0 and 1/n for any n. In this case x is infinitesimal. This is not true in the real numbers (R) given by ZFC. Nonetheless, the theorem proves that there is a model (a number system) in which this will be true. The question is: what is this model? What are its properties? Is there only one such model?

There are in fact many ways to construct such a one-dimensional linearly ordered set of numbers, but fundamentally, there are two different approaches:

1) Extend the number system so that it contains more numbers than the real numbers.
2) Extend the axioms (or extend the language) so that the distinction between the infinitesimals and non-infinitesimals can be made in the real numbers themselves.

In 1960, Abraham Robinson provided an answer following the first approach. The extended set is called the hyperreals and contains numbers less in absolute value than any positive real number. The method may be considered relatively complex but it does prove that infinitesimals exist in the universe of ZFC set theory. The real numbers are called standard numbers and the new non-real hyperreals are called nonstandard.

In 1977 Edward Nelson provided an answer following the second approach. The extended axioms are IST, which stands either for Internal Set Theory or for the initials of the three extra axioms: Idealization, Standardization, Transfer. In this system we consider that the language is extended in such a way that we can express facts about infinitesimals. The real numbers are either standard or nonstandard. An infinitesimal is a nonstandard real number which is less, in absolute value, than any positive standard real number.

In 2006 Karel Hrbacek developed an extension of Nelson's approach in which the real numbers are stratified in (infinitely) many levels; i.e., in the coarsest level there are no infinitesimals nor unlimited numbers. Infinitesimals are in a finer level and there are also infinitesimals with respect to this new level and so on.

Infinitesimals in teaching

Calculus textbooks based on infinitesimals include the classic Calculus Made Easy by Silvanus P. Thompson, and bearing the motto "What one fool can do another can".[11] Pioneering works based on Abraham Robinson's infinitesimals include texts by Stroyan (dating from 1972) and Howard Jerome Keisler (Elementary Calculus: An Infinitesimal Approach). Students easily relate to the intuitive notion of an infinitesimal difference 1-"0.999...", where "0.999..." differs from its standard meaning as the real number 1, and is reinterpreted as an infinite terminating extended decimal that is strictly less than 1.[12][13]

Template:Infinitesimals In mathematics, the Littlewood–Richardson rule is a combinatorial description of the coefficients that arise when decomposing a product of two Schur functions as a linear combination of other Schur functions. These coefficients are natural numbers, which the Littlewood–Richardson rule describes as counting certain skew tableaux. They occur in many other mathematical contexts, for instance as multiplicity in the decomposition of tensor products of irreducible representations of general linear groups (or related groups like the special linear and special unitary groups), or in the decomposition of certain induced representations in the representation theory of the symmetric group, or in the area of algebraic combinatorics dealing with Young tableaux and symmetric polynomials.

Littlewood–Richardson coefficients depend on three partitions, say , of which and describe the Schur functions being multiplied, and gives the Schur function of which this is the coefficient in the linear combination; in other words they are the coefficients such that

The Littlewood–Richardson rule states that is equal to the number of Littlewood–Richardson tableaux of skew shape and of weight .

History

Fitter (Standard ) Stephan Sampley from Nicolet, enjoys reading, top 20 property developers in singapore developers in singapore and aromatherapy. Have been recently gonna León Cathedral. The Littlewood–Richardson rule by Template:Harvs but though they claimed it as a theorem they only proved it in some fairly simple special cases. Template:Harvs claimed to complete their proof, but his argument had gaps, though it was so obscurely written that these gaps were not noticed for some time, and his argument is reproduced in the book Template:Harv. Some of the gaps were later filled by Template:Harvtxt. The first rigorous proofs of the rule were given four decades after it was found, by Template:Harvs and Template:Harvtxt, after the necessary combinatorial theory was developed by Template:Harvs, Template:Harvs, and Template:Harvs in their work on the Robinson–Schensted correspondence. There are now several short proofs of the rule, such as Template:Harv, and Template:Harv using Bender-Knuth involutions. Template:Harvtxt used the Littelmann path model to generalize the Littlewood–Richardson rule to other semisimple Lie groups.

The Littlewood–Richardson rule is notorious for the number of errors that appeared prior to its complete, published proof. Several published attempts to prove it are incomplete, and it is particularly difficult to avoid errors when doing hand calculations with it: even the original example in Template:Harvs contains an error.

The Littlewood–Richardson rule states that is equal to the number of Littlewood–Richardson tableaux of shape and of weight .

Littlewood–Richardson tableaux

A Littlewood–Richardson tableau

A Littlewood–Richardson tableau is a skew semistandard tableau with the additional property that the sequence obtained by concatenating its reversed rows is a lattice word (or lattice permutation), which means that in every initial part of the sequence any number occurs at least as often as the number . Another equivalent (though not quite obviously so) characterization is that the tableau itself, and any tableau obtained from it by removing some number of its leftmost columns, has a weakly decreasing weight. Many other combinatorial notions have been found that turn out to be in bijection with Littlewood–Richardson tableaux, and can therefore also be used to define the Littlewood–Richardson coefficients.

Another Littlewood–Richardson tableau

Example

Consider the case that , and . Then the fact that can be deduced from the fact that the two tableaux shown at the right are the only two Littlewood–Richardson tableaux of shape and weight . Indeed, since the last box on the first nonempty line of the skew diagram can only contain an entry 1, the entire first line must be filled with entries 1 (this is true for any Littlewood–Richardson tableau); in the last box of the second row we can only place a 2 by column strictness and the fact that our lattice word cannot contain any larger entry before it contains a 2. For the first box of the second row we can now either use a 1 or a 2. Once that entry is chosen, the third row must contain the remaining entries to make the weight (3,2,1), in a weakly increasing order, so we have no choice left any more; in both case it turns out that we do find a Littlewood–Richardson tableau.

A more geometrical description

The condition that the sequence of entries read from the tableau in a somewhat peculiar order form a lattice word, can be replaced by a more local and geometrical condition. Since in a semistandard tableau equal entries never occur in the same column, one can number the copies of any value from right to left, which is their order in of occurrence in the sequence that should be a lattice word. Call the number so associated to each entry its index, and write an entry i with index j as i[j]. Now if some Littlewood–Richardson tableau contains an entry occurs with index j, then that entry i[j] should occur in a row strictly below that of (which certainly also occurs, since the entry i − 1 occurs as least as often as the entry i does). In fact the entry i[j] should also occur in a column no further to the right than that same entry (which at first sight appears to be a stricter condition). If the weight of the Littlewood–Richardson tableau is fixed beforehand, then one can form a fixed collection of indexed entries, and the if these are placed in a way respecting those geometric restrictions, in addition to those of semistandard tableaux and the condition that indexed copies of the same entries should respect right-to-left ordering of the indexes, then the resulting tableaux are guaranteed to be Littlewood–Richardson tableaux.

An algorithmic form of the rule

The Littlewood–Richardson as stated above gives a combinatorial expression for individual Littlewood–Richardson coefficients, but gives no indication of a practical method to enumerate the Littlewood–Richardson tableaux in order to find the values of these coefficients. Indeed for given there is no simple criterion to determine whether any Littlewood–Richardson tableaux of shape and of weight exist at all (although there are a number of necessary conditions, the simplest of which is ); therefore it seems inevitable that in some cases one has to go through an elaborate search, only to find that no solutions exist.

Nevertheless, the rule leads to a quite efficient procedure to determine the full decomposition of a product of Schur functions, in other words to determine all coefficients for fixed λ and μ, but varying ν. This fixes the weight of the Littlewood–Richardson tableaux to be constructed and the "inner part" λ of their shape, but leaves the "outer part" ν free. Since the weight is known, the set of indexed entries in the geometric description is fixed. Now for successive indexed entries, all possible positions allowed by the geometric restrictions can be tried in a backtracking search. The entries can be tried in increasing order, while among equal entries they can be tried by decreasing index. The latter point is the key to efficiency of the search procedure: the entry i[j] is then restricted to be in a column to the right of , but no further to the right than (if such entries are present). This strongly restricts the set of possible positions, but always leaves at least one valid position for ; thus every placement of an entry will give rise to at least one complete Littlewood–Richardson tableau, and the search tree contains no dead ends.

A similar method can be used to find all coefficients for fixed λ and ν, but varying μ.

Littlewood–Richardson coefficients

The Littlewood–Richardson coefficients cTemplate:Sup sub   appear in the following ways:

or equivalently cTemplate:Sup sub   is the inner product of sν and sλsμ.
where σμ is the class of the Schubert variety of a Grassmannian corresponding to μ.
  • cTemplate:Sup sub   is the number of times the irreducible representation VλVμ of the product of symmetric groups S|λ| × S|μ| appears in the restriction of the representation Vν of S|ν| to S|λ| × S|μ|. By Frobenius reciprocity this is also the number of times that Vν occurs in the representation of S|ν| induced from VλVμ.
  • The cTemplate:Sup sub   appear in the decomposition of the tensor product Template:Harv of two Schur modules (irreducible representations of special linear groups)

Generalizations and special cases

Template:Harvtxt extended the Littlewood–Richardson rule to skew Schur functions as follows:

where the sum is over all tableaux T on μ/ν such that for all j, the sequence of integers λ+ω(Tj) is non-increasing, and ω is the weight.

Pieri's formula, which is the special case of the Littlewood–Richardson rule in the case when one of the partitions has only one part, states that

where Sn is the Schur function of a partition with one row and the sum is over all partitions λ obtained from μ by adding n elements to its Ferrers diagram, no two in the same column.

If both partitions are rectangular in shape, the sum is also multiplicity free Template:Harv. Fix a, b, p, and q positive integers with p q. Denote by the partition with p parts of length a. The partitions indexing nontrivial components of are those partitions with length such that

Examples

The examples of Littlewood-Richardson coefficients below are given in terms of products of Schur polynomials Sπ, indexed by partitions π, using the formula

All coefficients with ν at most 4 are given by:

  • S0Sπ = Sπ for any π. where S0=1 is the Schur polynomial of the empty partition
  • S1S1 = S2 + S11
  • S2S1 = S3 + S21
  • S11S1 = S111 + S21
  • S3S1 = S4 + S31
  • S21S1 = S31 + S22 + S211
  • S2S2 = S4 + S31 + S22
  • S2S11 = S31 + S211
  • S111S1 = S1111 + S211
  • S11S11 = S1111 + S211 + S22

Most of the coefficients for small partitions are 0 or 1, which happens in particular whenever one of the factors is of the form Sn or S11...1, because of Pieri's formula and its transposed counterpart. The simplest example with a coefficient larger than 1 happens when neither of the factors has this form:

  • S21S21 = S42 + S411 + S33 + 2S321 + S3111 + S222 + S2211.

For larger partitions the coefficients become more complicated. For example,

  • S321S321 = S642 +S6411 +S633 +2S6321 +S63111 +S6222 +S62211 +S552 +S5511 +2S543 +4S5421 +2S54111 +3S5331 +3S5322 +4S53211 +S531111 +2S52221 +S522111 +S444 +3S4431 +2S4422 +3S44211 +S441111 +3S4332 +3S43311 +4S43221 +2S432111 +S42222 +S422211 +S3333 +2S33321 +S333111 +S33222 +S332211 with 34 terms and total multiplicity 62, and the largest coefficient is 4
  • S4321S4321 is a sum of 206 terms with total multiplicity is 930, and the largest coefficient is 18.
  • S54321S54321 is a sum of 1433 terms with total multiplicity 26704, and the largest coefficient (that of S86543211) is 176.
  • S654321S654321 is a sum of 10873 terms with total multiplicity is 1458444 (so the average value of the coefficients is more than 100, and they can be as large as 2064).

The original example given by Template:Harvtxt was (after correcting for 3 tableaux they found but forgot to include in the final sum)

  • S431S221 = S652 + S6511 + S643 + 2S6421 + S64111 + S6331 + S6322 + S63211 + S553 + 2S5521 + S55111 + 2S5431 + 2S5422 + 3S54211 + S541111 + S5332 + S53311 + 2S53221 + S532111 + S4432 + S44311 + 2S44221 + S442111 + S43321 + S43222 + S432211

with 26 terms coming from the following 34 tableaux:

....11 ....11 ....11 ....11 ....11 ....11 ....11 ....11 ....11
