Supergroup (physics)
From Biocrawler, the free encyclopedia.
The concept of supergroup is a generalization of that of group.
[That means every group is a supergroup but not every supergroup is a group.]
First, let's define what a Hopf superalgebra is. Recall that a Hopf algebra is defined category theoretically over the category K-Vect. Similarly, a Hopf superalgebra is defined category theoretically over the category K-Z_2Vect, which is a Z2-graded category. The definitions are the same together with the additional requirement that the morphisms η, 
, ε, Δ and S are all even morphisms.
A Lie supergroup is a supermanifold G together with a morphism 
which makes G a group object in the category of supermanifolds. This is a generalization of a Lie group.
