#### An introduction to supermanifolds

###### Yigal Kamel (UIUC)

Abstract: Super mathematics concerns the extension of commutative mathematics to include the anti-commutative setting. For example, a superalgebra, is a Z/2-graded algebra which decomposes into commutative and anti-commutative summands. Accordingly, supermanifolds are the corresponding Z/2-graded generalization of manifolds. In this talk, I will introduce supermanifolds from two perspectives: the concrete approach, which constructs supermanifolds out of charts to a superspace (as with ordinary manifolds), and the algebro-geometric approach which extends the sheaf of continuous functions on a manifold to the super setting.
