Self-injective algebras under derived equivalences

Published 6 Oct 2023 in math.RT and math.RA | (2310.04012v3)

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.
