Hopf actions on filtered regular algebras
Kenneth Chan, Chelsea Walton, Yanhua Wang +1
We study finite dimensional Hopf algebra actions on so-called filtered Artin-Schelter regular algebras of dimension n, particularly on those of dimension 2. The first Weyl algebra…

Hopf actions and Nakayama automorphisms
Kenneth Chan, Chelsea Walton, James Zhang
Let H be a Hopf algebra with antipode S, and let A be an N-Koszul Artin-Schelter regular algebra. We study connections between the Nakayama automorphism of A and S^2 of H when H co…
