Noncommutative Auslander correspondence for semisimple Hopf actions

At least 9 years old · documented by

Let HH be a semisimple Hopf algebra and let AA be a noetherian Artin–Schelter regular, connected graded algebra generated in degree one. Suppose that AA is a graded HH-module algebra with an inner faithful action and trivial homological determinant, and that AH≠AA^H\neq A. Here A#HA\# H denotes the smash product and End⁡AH(A)\operatorname{End}_{A^H}(A) the endomorphism algebra of AA as a right AHA^H-module. Noncommutative Auslander conjecture. There is a natural graded algebra isomorphism

A#H≅End⁡AH(A).A\# H\cong \operatorname{End}_{A^H}(A).

This conjecture extends Auslander's theorem from small finite-group actions on commutative polynomial rings to semisimple Hopf actions on noetherian AS regular algebras. Its status is not established in the supplied text.
