Abstract
For a tensor ring , under certain conditions, we characterize the Gorenstein projective modules over , and prove that a -module is Gorenstein projective if and only if is monomorphic and is a Gorenstein projective -module. Gorenstein injective (resp., flat) modules over are also explicitly described. Moreover, we give a characterization for the coherence of . Some applications to trivial ring extensions and Morita context rings are given.
