Abstract

Let TR(M)T_R(M) be a tensor ring and X\mathcal{X}, Y\mathcal{Y} be two classes of RR-modules. Under certain conditions, we prove that a TR(M)T_R(M)-module (A,u)(A, u) is Ind(X)Ind(\mathcal{X})-Gorenstein projective if and only if uu is monomorphic and coker(u)coker(u) is an X\mathcal{X}-Gorenstein projective RR-module. Y\mathcal{Y}-Gorenstein injective TR(M)T_R(M)-modules are also explicitly described. As a consequence, the characterizations of Ding projective and Ding injective modules over TR(M)T_R(M) are obtained. Some applications to trivial ring extensions and Morita context rings are given.
