Finite generation of the cohomology of some skew group algebras

Published 2 Oct 2013 in math.RT and math.RA | (1310.0724v4)

Abstract: We prove that some skew group algebras have Noetherian cohomology rings, a property inherited from their component parts. The proof is an adaptation of Evens' proof of finite generation of group cohomology. We apply the result to a series of examples of finite dimensional Hopf algebras in positive characteristic.
