On simple-minded systems over representation-finite self-injective algebras

Representation Theory 2020-06-26 v1

Abstract

Let AA be a representation-finite self-injective algebra over an algebraically closed field kk. We give a new characterization for an orthogonal system in the stable module category AA-\stmod\stmod to be a simple-minded system. As a by-product, we show that every Nakayama-stable orthogonal system in AA-\stmod\stmod extends to a simple-minded system.
