Gorenstein Projective Modules Over Triangular Matrix Rings
arXiv:1402.4595
Abstract
We study totally acyclic complexes of projective modules over triangular matrix rings and then use it to classify Gorenstein projective modules over such rings. We also use this classification to obtain some information concerning Cohen-Macaulay finite and virtually Gorenstein triangular matrix artin algebras.
