Noncommutative Auslander correspondence for semisimple Hopf actions
Let be a semisimple Hopf algebra and let be a noetherian Artin–Schelter regular, connected graded algebra generated in degree one. Suppose that is a graded -module algebra with an inner faithful action and trivial homological determinant, and that . Here denotes the smash product and the endomorphism algebra of as a right -module. Noncommutative Auslander conjecture. There is a natural graded algebra isomorphism
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.
