Abstract
When and is a small subgroup of , Auslander's Theorem says that the skew group algebra is isomorphic to as graded algebras. We prove a generalization of Auslander's Theorem for permutation actions on -skew polynomial rings, -quantum Weyl algebras, three-dimensional Sklyanin algebras, and a certain graded down-up algebra. We also show that certain fixed rings are graded isolated singularities in the sense of Ueyama.
