Abstract
Let be a tensor ring and , be two classes of -modules. Under certain conditions, we prove that a -module is -Gorenstein projective if and only if is monomorphic and is an -Gorenstein projective -module. -Gorenstein injective -modules are also explicitly described. As a consequence, the characterizations of Ding projective and Ding injective modules over are obtained. Some applications to trivial ring extensions and Morita context rings are given.
