Abstract

I present a construction of connected affine algebraic supergroups š†V associated with simple Lie superalgebras š”¤ of Cartan type and with š”¤-modules V. Conversely, I prove that every connected affine algebraic supergroup whose tangent Lie superalgebra is of Cartan type is necessarily isomorphic to one of the supergroups š†V that I introduced. In particular, the supergroup associated in this way with š”¤=W(n) and its standard representation is described.

The author thanks P. Cartier, M. Duflo, R. Fioresi, V. Serganova for many useful conversations and hints.
