On actions of connected algebraic groups

Abstract

We obtain a version of the theorem of the square and a local structure result for actions of connected algebraic groups on seminormal varieties in characteristic 0, and arbitrary varieties in positive characteristics.

This preprint has been withdrawn by the author, since it will be split in two forthcoming preprints
