Reductivity properties over an affine base

Research output: Contribution to journal › Article › Academic › peer-review

Abstract

When the base ring is not a field, power reductivity of a group scheme is a basic notion, intimately tied with finite generation of subrings of invariants. Geometric reductivity is weaker and less pertinent in this context. We give a survey of these properties and their connections.
