讲座简介：

The centralizer algebras of matrices occur in geometry variety, doubly stochastic process, and invariant theory. In this talk, we are interested in relations between two centralizer algebras. Mainly, we describe Morita and derived equivalences of these algebras by new equivalence relations on matrices. The talk reports a work jointly with Xiaogang Li.
