Gorenstein homological dimension with respect to a semidualizing module and a generalization of a theorem of Bass
Let C be a semidualizing module for a commutative ring R. In this paper, we study the
resulting modules of finite GC-projective dimension in Bass class, showing that they admit …

Homological dimensions, the Gorenstein property, and special cases of some conjectures
Our purpose in this work is multifold. First, we provide general criteria for the finiteness of the
projective and injective dimensions of a finite module $ M $ over a (commutative) …
