In [[mathematics]], a '''quasisymmetric''' [[homeomorphism]] between metric spaces is a map that generalizes [[lipschitz function|bi-Lipschitz]] maps. While bi-Lipschitz maps shrink or expand the diameter of a set by no more than a multiplicative factor, quasisymmetric maps satisfy the weaker geometric property that they preserve the relative sizes of sets: if two sets ''A'' and ''B'' have diameters ''t'' and are no more than distance ''t'' apart, then the ratio of their sizes changes by no more than a multiplicative constant. These maps are also related to [[quasiconformal]] maps, since in many circumstances they are in fact equivalent.<ref>{{cite book| last = Heinonen| first = Juha | title = Lectures on Analysis on Metric Spaces | series = Universitext | publisher = Springer-Verlag | address = New York | year = 2001 | pages = x+140 | ISBN = 0-387-95104-0}}</ref>
 
==Definition==
 
Let (''X'',&nbsp;''d''<sub>''X''</sub>) and (''Y'',&nbsp;''d''<sub>''Y''</sub>) be two [[metric space]]s. A [[homeomorphism]] ''f'':''X''&nbsp;→&nbsp;''Y'' is said to be '''η-quasisymmetric''' if there is an increasing function ''η''&nbsp;:&nbsp;[0,&nbsp;∞)&nbsp;→&nbsp;[0,&nbsp;∞) such that for any triple ''x'',&nbsp;''y'',&nbsp;''z'' of distinct points in ''X'', we have
 
:<math> \frac{d_Y(f(x),f(y))}{d_{Y}(f(x),f(z))} \leq \eta\left(\frac{d_X(x,y)}{d_X(x,z)}\right). </math>
 
==Basic properties==
 
; Inverses are quasisymmetric : If ''f''&nbsp;:&nbsp;''X''&nbsp;→&nbsp;''Y'' is an invertible ''η''-quasisymmetric map as above, then its inverse map is ''ή''-quasisymmetric, where ''ή''(''t'')&nbsp;=&nbsp;1/''η''(1/''t'').
; Quasisymmetric maps preserve relative sizes of sets : If ''A'' and ''B'' are subsets of ''X'' and ''A'' is a subset of ''B'', then
:: <math> \frac{1}{2\eta(\frac{\text{diam }B}{\text{diam }A})}\leq \frac{\text{diam }f(B)}{\text{diam }f(A)}\leq \eta\left(\frac{\text{diam }B}{\text{diam }A}\right).</math>
 
==Examples==
 
===Weakly quasisymmetric maps===
 
A map ''f:X→Y'' is said to be '''H-weakly-quasisymmetric''' for some ''H''&nbsp;>&nbsp;0 if for all triples of distinct points ''x,y,z'' in ''X'', we have
:<math> |f(x)-f(y)|\leq H|f(x)-f(z)|\;\;\;\text{ whenever }\;\;\; |x-y|\leq |x-z|</math>
 
Not all weakly quasisymmetric maps are quasisymmetric. However, if ''X'' is [[Connected space|connected]] and [[doubling measures and metric spaces|doubling]], then all weakly quasisymmetric maps are quasisymmetric. The appeal of this result is that proving weak-quasisymmetry is much easier than proving quasisymmetry directly, and in many natural settings we have the luck of knowing the two are equivalent.
 
===δ-monotone maps===
 
A [[Monotone_map#Monotonicity_in_functional_analysis|monotone map]] ''f'':''H''&nbsp;→&nbsp;''H'' on a [[Hilbert space]] ''H'' is '''δ-monotone''' if for all ''x'' and ''y'' in ''H'',
:<math> \langle f(x)-f(y),x-y\rangle\geq \delta |f(x)-f(y)|\cdot|x-y|.</math>
 
To grasp what this condition means geometrically, suppose ''f''(0)&nbsp;=&nbsp;0 and consider the above estimate when ''y''&nbsp;=&nbsp;0. Then it implies that the angle between the vector ''x'' and its image ''f''(''x'') stays between 0 and arccos&nbsp;''δ''&nbsp;<&nbsp;''π''/2.
 
These maps are quasisymmetric, although they are a much narrower subclass of quasisymmetric maps. For example, while a general quasisymmetric map in the complex plane could map the real line to a set of [[Hausdorff dimension]] strictly greater than one, a ''δ''-monotone will always map the real line to a rotated [[Graph of a function|graph]] of a Lipschitz function ''L'':ℝ&nbsp;→&nbsp;ℝ.<ref>{{cite journal | last = Kovalev | first = Leonid V. | title= Quasiconformal geometry of monotone mappings | journal = Journal of the London Mathematical Society | volume = 75 | year = 2007 | number = 2 | pages = 391–408}}</ref>
 
==Quasisymmetric maps and doubling measures==
 
===The real line===
 
Quasisymmetric homeomorphisms of the [[real line]] to itself can be characterized in terms of their derivatives.<ref>{{cite journal| last = Beurling | first = A. | coauthors = [[Lars Ahlfors|Ahlfors, L.]] | title = The boundary correspondence under quasiconformal mappings | journal = Acta Math. | volume= 96 | year = 1956 | pages = 125–124}}</ref> An increasing homeomorphism ''f'':ℝ&nbsp;→&nbsp;ℝ is quasisymmetric if and only if there is a constant ''C''&nbsp;>&nbsp;0 and  a [[doubling measures and metric spaces|doubling measure]] ''μ'' on the real line such that
 
:<math> f(x)=C+\int_0^x \, d\mu(t).</math>
 
===Euclidean space===
 
An analogous result holds in Euclidean space. Suppose ''C''&nbsp;=&nbsp;0 and we rewrite the above equation for ''f'' as  
:<math> f(x) = \frac{1}{2}\int_{\mathbb{R}}\left(\frac{x-t}{|x-t|}+\frac{t}{|t|}\right)d\mu(t).</math>
 
Writing it this way, we can attempt to define a map using this same integral, but instead integrate (what is now a vector valued integrand) over ℝ<sup>''n''</sup>: if ''μ'' is a doubling measure on ℝ<sup>''n''</sup> and
:<math> \int_{|x|>1}\frac{1}{|x|}\,d\mu(x)<\infty</math>
then the map
:<math> f(x) = \frac{1}{2}\int_{\mathbb{R}^{n}}\left(\frac{x-y}{|x-y|}+\frac{y}{|y|}\right)\,d\mu(y)</math>
is quasisymmetric (in fact, it is ''δ''-monotone for some ''δ'' depending on the measure ''μ'').<ref>{{cite journal| last = Kovalev | first = Leonid | last2 = Maldonado | first2 = Diego | last3 = Wu | first3 = Jang-Mei | title = Doubling measures, monotonicity, and quasiconformality |journal= Math.

==Quasisymmetry and quasiconformality in Euclidean space==
 
Let ''Ω'' and ''Ω´'' be open subsets of ℝ<sup>''n''</sup>. If ''f''&nbsp;:&nbsp;Ω&nbsp;→&nbsp;Ω´ is ''η''-quasisymmetric, then it is also ''K''-[[quasiconformal]], where ''K''&nbsp;>&nbsp;0 is a constant depending on ''η''.
 
Conversely, if ''f''&nbsp;:&nbsp;Ω&nbsp;→&nbsp;Ω´ is ''K''-quasiconformal and ''B''(''x'',&nbsp;2''r'') is contained in ''Ω'', then ''f'' is ''η''-quasisymmetric on ''B''(''x'',&nbsp;''r''), where ''η'' depends only on&nbsp;''K''.

A heat sink is responsible for taking the heat out of the LED and moving it away from the lighting program. With the substantial initial investment that is required to setup an LED grow, you cannot take chances.

For plants that will need added light, or for additional power during flowering, they would add in LED panels in particular places considering that they are so simply attached without taking up space. Now, nevertheless, there are effective, and substantially larger, LED panels that can provide an whole grow room with vibrant light that keeps your plants wholesome and lucrative. Quite a few men and women make the error of only using a single sort of LED grow light.

Advanced LED is established to be 1 of the most effective LED grow lights suppliers on the marketplace. Their products perform far above most of the other develop lights you may stumble upon even though browsing in the net.  They spent many years operating in grow lights market and have been perfecting their goods each year. That hands on practice guarantees that every develop light is of the highest good quality.

These lights do not use electrodes or filaments, like classic lighting systems do. In reality, they offer a great number of rewards more than most sorts of grow lights. Plasma Grow Lights present the very same full spectrum light that fluorescent and HPS systems present, incredible levels of efficiency, and save space compared to lights that call for ballasts and in depth wiring harnesses.

With T5 LED tubes, there are possibilities that measure 4 feet in length and can cover quite a few much more square feet than standard LED lights and greatly simplify the quantity of gear that is hanging from the ceiling of your grow area. T5 LED grow lamps aren't the most perfect choice for quite a few growers, but they are a quite high top quality option for keeping points very simple when you would like to use the highest top quality technologies offered.
