	~~In [[mathematics]], an '''antihomomorphism'''~~ is ~~a type of [[Function (mathematics)\|function]] defined on sets~~ with ~~multiplication~~ that ~~reverses the [[Noncommutative\|order of multiplication]]. An '''antiautomorphism''' is an antihomomorphism which~~ has ~~an inverse as an antihomomorphism; this coincides with~~ it ~~being a [[bijection]] from an object~~ to ~~itself~~.

	~~==Definition==~~
	~~Informally~~, ~~an antihomomorphism is map that switches~~ the ~~order of multiplication~~.

	~~Formally, an antihomomorphism between~~ ''~~X'' and ''Y'' is a homomorphism <math>\phi\colon X \~~to ~~Y^{\text{op}}</math>~~, ~~where~~ <~~math~~>~~Y^{\text{op}}~~<~~/math~~> ~~equals ''Y'' as~~ a ~~set~~, ~~but~~ has ~~multiplication reversed: denoting the multiplication~~ on ~~''Y'' as <math>\cdot</math> and~~ the ~~multiplication on <math>Y^{\text{op}}</math> as <math></math>~~, we have ~~<math>xy := y\cdot x</math>~~. The ~~object <math>Y^{\text{op}}</math>~~ is ~~called~~ the ~~'''opposite object'''~~ to '~~'Y''. (Respectively~~, ~~'''[[opposite group]]''', '''[[opposite algebra]]''', etc.)~~

	~~This definition is equivalent~~ to ~~a homomorphism <math>\phi\colon X^{\text{op}} \~~to ~~Y</math> (reversing~~ the ~~operation before or after applying~~ the ~~map is equivalent)~~. ~~Formally, sending ''X'' to~~ <~~math~~>~~X^{\text{op}}~~<~~/math~~> ~~and acting as~~ the ~~identity on maps~~ is ~~a [[functor]] (indeed, an [[Involution (mathematics)\|involution]])~~.

	~~==Examples==~~
	~~In [[group theory]]~~, ~~an antihomomorphism is~~ a ~~map between two groups that reverses the order of multiplication~~. ~~So if φ : ''X'' → ''Y''~~ is ~~a group antihomomorphism,~~
	~~:φ(''xy'') = φ(''y'')φ(''x'')~~
	~~for all ''x'', ''y'' in ''X''~~.

	The ~~map that sends ''x''~~ to ~~''x''~~<~~sup~~>−1<~~/sup~~> is ~~an example of a group antiautomorphism~~. ~~Another important example is~~ the ~~[[transpose]] operation~~ in ~~[[linear algebra]] which takes [[row vector]]s~~ to ~~[[column vector]]s~~. ~~Any vector-matrix equation may~~ be ~~transposed~~ to ~~an equivalent equation where the order~~ of ~~the factors~~ is ~~reversed.~~

	~~With matrices, an example~~ of ~~an antiautomorphism is given by~~ the ~~transpose map~~. ~~Since inversion and transposing both give antiautomorphisms, their composition is an automorphism. This involution is often called~~ the ~~contragredient map,~~ and ~~it provides an example of an outer automorphism~~ of ~~the general linear group GL(n,F) where F~~ is a ~~field~~, ~~except~~ when ~~\|F\|= 2 and n= 1 or 2 or \|F\| = 3 and n=1 (i~~.~~e., for~~ the ~~groups GL(1~~,~~2), GL(2,2), and GL(1,3))~~

	In [~~[ring theory~~]~~], an antihomomorphism~~ is ~~a map between two rings that preserves addition, but reverses~~ the ~~order~~ of ~~multiplication~~. ~~So φ : ''X'' → ''Y'' is~~ a ~~ring antihomomorphism if and only if:~~
	~~:φ(1) =~~ 1
	~~:φ(''x''+''y'') = φ(''x'')+φ(''y'')~~
	~~:φ(''xy'') = φ(''y'')φ(''x'')~~
	~~for all ''x''~~, ~~''y'' in ''X''~~.<~~ref~~>{{cite book \| title=The Theory of Rings \| series=Mathematical Surveys and Monographs \| volume=2 \| first=Nathan \| last=Jacobson \| authorlink=Nathan Jacobson \| publisher=[[American Mathematical Society]] \| year=1943 \| isbn=0821815024 \| page=16 }}<~~/ref~~>

	~~For [[algebra over a field\|algebras over a field]] ''K'', φ must be a ''K''-[[linear map]]~~ of the ~~underlying [[vector space]]. If~~ the ~~underlying field has an involution, one can instead ask φ to be [[conjugate~~-~~linear]], as in conjugate transpose, below.~~

	~~===Involutions===~~
	It is ~~frequently~~ the ~~case~~ that ~~antiautomorphisms~~ are ~~[[involution (mathematics)\|involution]]s, i.e~~. the ~~square of~~ the ~~antiautomorphism~~ is the ~~[[identity function\|identity map]];~~ these ~~are also called '''{{visible anchor\|involutive antiautomorphism}}s''~~'.

	* The map that sends ''x'' to ~~its [[inverse element\|inverse]] ''x''~~<~~sup~~>−1<~~/sup~~> ~~is an involutive antiautomorphism in any group.~~

	~~A ring with an involutive antiautomorphism is called a [[-ring]]~~, ~~and [[-algebra#Examples\|these form an important class of examples]].~~

	~~==Properties==~~
	If the ~~target ''Y'' is [[commutative]], then an antihomomorphism is the same~~ thing ~~as a [[homomorphism]] and an antiautomorphism is~~ the ~~same thing as an [[automorphism]].~~

	~~The [[function composition\|composition]] of two antihomomorphisms~~ is ~~always a homomorphism, since reversing the order twice preserves order. The composition of~~ an ~~antihomomorphism with~~ a ~~homomorphism gives another antihomomorphism~~.

Formally, an antihomomorphism between ''X'' and ''Y'' is a homomorphism <math>\phi\colon X \to Y^{\text{op}}</math>, where <math>Y^{\text{op}}</math> equals ''Y'' as a set, but has multiplication reversed: denoting the multiplication on ''Y'' as <math>\cdot</math> and the multiplication on <math>Y^{\text{op}}</math> as <math></math>, we have <math>xy := y\cdot x</math>. The object <math>Y^{\text{op}}</math> is called the '''opposite object''' to ''Y''. (Respectively, '''[[opposite group]]''', '''[[opposite algebra]]''', etc.)

			This definition is equivalent to a homomorphism <math>\phi\colon X^{\text{op}} \to Y</math> (reversing the operation before or after applying the map is equivalent). Formally, sending ''X'' to <math>X^{\text{op}}</math> and acting as the identity on maps is a [[functor]] (indeed, an [[Involution (mathematics)\|involution]]).

			==Examples==
			In [[group theory]], an antihomomorphism is a map between two groups that reverses the order of multiplication. So if φ : ''X'' → ''Y'' is a group antihomomorphism,
			:φ(''xy'') = φ(''y'')φ(''x'')
			for all ''x'', ''y'' in ''X''.

			The map that sends ''x'' to ''x''<sup>−1</sup> is an example of a group antiautomorphism. Another important example is the [[transpose]] operation in [[linear algebra]] which takes [[row vector]]s to [[column vector]]s. Any vector-matrix equation may be transposed to an equivalent equation where the order of the factors is reversed.

			With matrices, an example of an antiautomorphism is given by the transpose map. Since inversion and transposing both give antiautomorphisms, their composition is an automorphism. This involution is often called the contragredient map, and it provides an example of an outer automorphism of the general linear group GL(n,F) where F is a field, except when \|F\|= 2 and n= 1 or 2 or \|F\| = 3 and n=1 (i.e., for the groups GL(1,2), GL(2,2), and GL(1,3))

			In [[ring theory]], an antihomomorphism is a map between two rings that preserves addition, but reverses the order of multiplication. So φ : ''X'' → ''Y'' is a ring antihomomorphism if and only if:
			:φ(1) = 1
			:φ(''x''+''y'') = φ(''x'')+φ(''y'')
			:φ(''xy'') = φ(''y'')φ(''x'')

			For [[algebra over a field\|algebras over a field]] ''K'', φ must be a ''K''-[[linear map]] of the underlying [[vector space]]. If the underlying field has an involution, one can instead ask φ to be [[conjugate-linear]], as in conjugate transpose, below.

			A ring with an involutive antiautomorphism is called a [[-ring]], and [[-algebra#Examples\|these form an important class of examples]].

			==Properties==
			If the target ''Y'' is [[commutative]], then an antihomomorphism is the same thing as a [[homomorphism]] and an antiautomorphism is the same thing as an [[automorphism]].
