摘要：In this talk, we will discuss homological behaviors of centralizer matrix algebras. Specifically, we prove that each principal centralizer matrix algebra is Frobenius-finite, 1-Auslander-Gorenstein and gendo-symmetric. Further, we show that the Auslander-Reiten conjecture on stable equivalences holds true for principal centralizer matrix algebras over an algebraically closed field. This is based on a joint work with Professor Changchang Xi.
