摘 要: Morita, derived and stable equivalences are three of the most important equivalence relations in representation theory. In this talk, we concentrate us on understanding these relations between the centralizers of matrices. This class of algebras appears in geometry variety, Markov process and invariant theory. They are traced back to Ferdinand Georg Frobenius(1849-1917). We characterize these algebraic relations by elementary divisors and truncated polynomial algebras. For more details, see preprint arXiv:2312.08794.
