摘要
We investigate the endomorphism algebras Gamma of finite dimensional modules having the property that every indecomposable finite dimensional Gamma-module is of projective dimension at most one or injective dimension at most one. In particular, we describe all matrix algebras [GRAPHICS] with this homological property.
