A description of Gorenstein projective modules over the tensor products   of algebras
  Let $A$ be a coherent algebra and $B$ be a finite-dimensional Gorenstein algebra over a field $k$. We describe finitely presented Gorenstein projective $A\otimes_k B$-modules in terms of their underlying onesided modules. Moreover, if the global dimension of $B$ is finite, we give a more precise description of finitely presented Gorenstein projective $A\otimes_k B$-modules.
