Abstract

Let Λ \Lambda be an Artin algebra. This paper presents a condition that is necessary for a subcategory of mod Λ \bmod \Lambda to be contravariantly finite. Several examples are explored in the case that Λ \Lambda is the group algebra of a finite group over a field of finite characteristic.
