Abstract:We introduce the concepts of generalized compatible and cocompatible bimodules in order to characterize Gorenstein projective, injective and flat modules over trivial ring extensions. Let R ⋉ M be a trivial extension of a ring R by→ X is exact and coker(α) is a Gorenstein projective left R-module. Analogously, we explicitly characterize Gorenstein injective and flat modules over trivial ring extensions. As an application, we describe Gorenstein projective, injective and flat modules over Morita context rings w… Show more
