Stable equivalences and homological dimensions
Xiaogang Li, Changchang Xi
As is known, every finite-dimensional algebra over a field is isomorphic to the centralizer algebra of \textbf{two} matrices. So it is fundamental to study first the centralizer al…

Derived equivalences, new matrix equivalences, and homological conjectures
Xiaogang Li, Changchang Xi
Based on the fact that every finite-dimensional algebra over a field is isomorphic to the centralizer of \textbf{two} matrices, we approach the representation theory of finite-dime…
