Self-injective algebras under derived equivalences

Representation Theory 2024-10-29 v3 Rings and Algebras

Abstract

The Nakayama permutations of two derived equivalent, self-injective Artin algebras are conjugate. A different but elementary approach is given to showing that the weak symmetry and self-injectivity of finite-dimensional algebras over an arbitrary field are preserved under derived equivalences.
