# Chevalley Supergroups

Share this page
*R. Fioresi; F. Gavarini*

In the framework of algebraic supergeometry, the authors give a
construction of the scheme-theoretic supergeometric analogue of split reductive
algebraic group-schemes, namely affine algebraic supergroups associated to
simple Lie superalgebras of classical type. In particular, all Lie
superalgebras of both basic and strange types are
considered. This provides a unified approach to most of the algebraic
supergroups considered so far in the literature, and an effective method to
construct new ones.

The authors' method follows the pattern of a suitable scheme-theoretic
revisitation of Chevalley's construction of semisimple algebraic
groups, adapted to the reductive case. As an intermediate step, they
prove an existence theorem for Chevalley bases of simple classical Lie
superalgebras and a PBW-like theorem for their associated Kostant
superalgebras.
