Modular group actions on algebras and p-local Galois extensions for finite groups
Peter Fleischmann, Chris Woodcock
Let k be a field of positive characteristic p and let G be a finite group. In this paper we study the category TsG of finitely generated commutative k-algebras A on which G acts by…

Non-linear Group Actions with Polynomial Invariant Rings and a Structure Theorem for Modular Galois Extensions
Peter Fleischmann, Chris Woodcock
Let be a finite -group and a field of characteristic . We show that has a \emph{non-linear} faithful action on a polynomial ring of dimension $n=\mathrm{log…
