Invariants and separating morphisms for algebraic group actions
The first part of this paper is a refinement of Winkelmann’s work on invariant rings and quotients of algebraic group actions on affine varieties, where we take a more geometric point of view. We show that the (algebraic) quotient X//GX//G given by the possibly not finitely generated ring of inva...
