ul 2 00 1 Invariants of finite group schemes

Abstract

Let k be an algebraically closed field, G a finite group scheme over k operating on a scheme X over k. Under assumption that X can be covered by G-invariant affine open subsets the classical results in [3] and [14] describe the quotient X/G. In case of a free action X is known to be a principal homogeneous G-space over X/G. Furthermore, the category of G… (More)
