报告摘要:In the talk we investigate homological data of algebras like delooping levels and Igusa-Todorov’s dimensions, and show that they are invariant under stable equivalences. Moreover, we show that the numbers of non-isomorphic, non-projective simple modules of centralizer matrix algebras are invariant under stable equivalences, that is, the Auslander–Reiten conjecture on stable equivalences holds true for such algebras. Further, we show that the finitistic dimension conjecture and Nakayama conjecture are also true for centralizer matrix algebras. The contents of this talk present parts of a joint work with Jin Zhangat and with Jinbi Zhang.
