报告摘要:
Stable equivalences of algebras are of great interest in the representation theory of algebras. The Auslander-Reiten (or Auslander-Alperin) conjecture on stable equivalences, which states that the numbers of non-isomorphic, non-projective simple modules of algebras are invariant under stable equivalences, seems still to be understood. In this talk, we consider the conjecture for a class of centralizer matrix subalgebras and show that the above-mentioned conjecture is true for these algebras. Also, structural and homological properties of centralizer matrix subalgebras will be reported. The contents of the talk are from joint works with Jinbi Zhang.
