			== Definition ==
			Given two [[dual pair]]s [[separated space\|separated]] [[locally convex space]]s <math>\left(X,X^\right)</math> and <math>\left(Y,Y^\right)</math>. Then given the function <math>f: X \to \mathbb{R} \cup \{+\infty\}</math>, we can define the primal problem by

			:<math>\inf_{x \in X} f(x). \, </math>

			If there are constraint conditions, these can be built into the function <math>f</math> by letting <math>f = f + I_\mathrm{constraints}</math> where <math>I</math> is the [[Characteristic function (convex analysis)\|indicator function]]. Then <math>F: X \times Y \to \mathbb{R} \cup \{+\infty\}</math> is a ''perturbation function'' if and only if <math>F(x,0) = f(x)</math>.<ref name="BWG" /><ref name="Zalinescu">{{cite book\|last=Zălinescu\|first=C.\|title=Convex analysis in general vector spaces\|publisher=World Scientific Publishing  Co., Inc\|location = River Edge, NJ, \|year=2002\|pages=106–113\|isbn=981-238-067-1\|mr=1921556}}</ref>

			== Use in duality ==
			The [[duality gap]] is the difference of the right and left hand side of the inequality
			:<math>\sup_{y^* \in Y^} -F^(0,y^*) \le \inf_{x \in X} F(x,0),</math>
			where <math>F^*</math> is the [[convex conjugate]] in both variables.<ref name="Zalinescu" /><ref>{{cite book\|title=Overcoming the failure of the classical generalized interior-point regularity conditions in convex optimization. Applications of the duality theory to enlargements of maximal monotone operators\|author=Ernö Robert Csetnek\|year=2010\|publisher=Logos Verlag Berlin GmbH\|isbn=978-3-8325-2503-3}}</ref>

			For any choice of perturbation function ''F'' [[weak duality]] holds. There are a number of conditions which if satisfied imply [[strong duality]].<ref name="Zalinescu" /> For instance, if ''F'' is [[proper convex function\|proper]], jointly [[convex function\|convex]], [[lower semi-continuous]] with <math>0 \in \operatorname{core}(\operatorname{Pr}_Y(\operatorname{dom}F))</math> (where <math>\operatorname{core}</math> is the [[algebraic interior]] and <math>\operatorname{Pr}_Y</math> is the [[projection (set theory)\|projection]] onto ''Y'' defined by <math>\operatorname{Pr}_Y(x,y) = y</math>) and ''X'', ''Y'' are [[Fréchet space]]s then strong duality holds.<ref name="BWG" />

			== Examples ==

			=== Lagrangian ===
			Let <math>(X,X^)</math> and <math>(Y,Y^)</math> be dual pairs. Given a primal problem (minimize ''f(x)'') and a related perturbation function (''F(x,y)'') then the '''Lagrangian''' <math>L: X \times Y^* \to \mathbb{R} \cup \{+\infty\}</math> is the negative conjugate of ''F'' with respect to ''y'' (i.e. the concave conjugate). That is the Lagrangian is defined by
			:<math>L(x,-y^) = \inf_{y \in Y} \left\{F(x,y) - y^(y)\right\}.</math>
			In particular the [[weak duality]] minmax equation can be shown to be
			:<math>\sup_{y^* \in Y^} -F^(0,y^) = \sup_{y^ \in Y^} \inf_{x \in X} L(x,y^) \leq \inf_{x \in X} \sup_{y^* \in Y^} L(x,y^) = \inf_{x \in X} F(x,0).</math>

			If the primal problem is given by
			:<math>\inf_{x: g(x) \leq 0} f(x) = \inf_{x \in X} \tilde{f}(x)</math>
			where <math>\tilde{f}(x) = f(x) + I_{\mathbb{R}^d_+}(-g(x))</math>. Then if the perturbation is given by
			:<math>\inf_{x: g(x) \leq y} f(x)</math>
			then the perturbation function is
			:<math>F(x,y) = f(x) + I_{\mathbb{R}^d_+}(y - g(x))</math>.
			Thus the connection to Lagrangian duality can be seen, as ''L'' can be trivially seen to be
			:<math>L(x,y^*) = \begin{cases}
			f(x) + y^(g(x)) & \text{if } y^ \in \mathbb{R}^d_+\\
			-\infty & \text{else}
			\end{cases}</math>.

			=== Fenchel duality ===
			{{main\|Fenchel duality}}
			Let <math>(X,X^)</math> and <math>(Y,Y^)</math> be dual pairs. Assume there exists a [[linear map]] <math>T: X \to Y</math> with [[adjoint operator]] <math>T^: Y^ \to X^*</math>. Assume the primal [[objective function]] <math>f(x)</math> (including the constraints by way of the indicator function) can be written as <math>f(x) = J(x,Tx)</math> such that <math>J: X \times Y \to \mathbb{R} \cup \{+\infty\}</math>. Then the perturbation function is given by
			: <math>F(x,y) = J(x,Tx - y)</math>.

			In particular if the primal objective is <math>f(x) + g(Tx)</math> then the perturbation function is given by <math>F(x,y) = f(x) + g(Tx - y)</math>, which is the traditional definition of [[Fenchel duality]].<ref>{{cite book\|title=Conjugate Duality in Convex Optimization\|author=Radu Ioan Boţ\|publisher=Springer\|year=2010\|isbn=978-3-642-04899-9\|page=68}}</ref>

Whether it be making money or losing money, updates ought to be brought upon and discussed nicely to function both as a means to recognize those which have done a superb job and in precisely the same time encourage those that have not been able to do much. Here are charity team building activities tips that will help your company grow better using a team that is better.
