-The concept of '''supergroup''' is a [[generalization]] of that of [[group (mathematics)|group]].  In other words, every supergroup carries a natural group structure, and vice versa, but there may be more than one way to structure a given group as a supergroup. A supergroup is like a Lie group in that there is a well defined notion of [[smooth function]] defined on them.
+Sky+ HD 1TB <br>x
-However the functions may have even and odd parts. Moreover a supergroup has a [[super Lie algebra]] which plays a role similar to that of a [[Lie algebra]] for Lie groups in that they determine most of the representation theory and which is the starting point for classification.

-More formally, a '''Lie supergroup''' is a [[supermanifold]] G together with a multiplication morphism <math>\mu :G \times G\rightarrow G</math>, an inversion morphism <math>i : G \rightarrow G</math> and a unit morphism <math>e:  1 \rightarrow G</math> which makes G a [[group object]] in the [[category theory|category]] of supermanifolds. This means that, formulated as commutative diagrams, the usual associativity and inversion axioms of a group continue to hold. Since every manifold is a super manifold, a Lie supergroup generalises the notion of a [[Lie group]].

-There are many possible supergroups. The ones of most interest in theoretical physics are the ones which extend the [[Poincaré group]] or the [[conformal group]]. Of particular interest are the  '''orthosymplectic groups''' ''Osp(N/M)'' and the '''superconformal groups''' ''SU(N/M)''.

-An equivalent algebraic approach starts from the observation that a super manifold is determined by its ring of [[supercommutative]] smooth functions, and that a morphism of super manifolds corresponds one to one with an algebra homomorphism between their functions in the opposite direction, i.e. that the category of supermanifolds is opposite to the category of algebras of smooth graded commutative functions.  Reversing all the arrows in the commutative diagrams that define a Lie supergroup then shows that functions over the supergroup have the structure of a '''Z'''<sub>2</sub>-graded [[Hopf algebra]]. Likewise the representations of this Hopf algebra turn out to be '''Z'''<sub>2</sub>-graded [[comodule]]s. This Hopf algebra gives the global properties of the supergroup.

-There is another related Hopf algebra which is the dual of the previous Hopf algebra. It can be identified with the Hopf algebra of graded differential operators at the origin. It only gives the local properties of the symmetries i.e., it only gives information about infinitesimal supersymmetry transformations. The representations of this Hopf algebra are [[Module (mathematics)|module]]s. Like in the non graded case, this Hopf algebra can be described purely algebraically as the [[universal enveloping algebra]] of the [[Lie superalgebra]].
