Let R be a commutative Noetherian ring. We prove that over a local ring R every finitely generated R-module M of finite Gorenstein projective dimension has a Gorenstein projective cover\varphi:C \rightarrow M such that C is finitely generated and the projective dimension of \Ker\varphi is finite and \varphi is surjective.
کلمات کلیدی: Cover, Precover, Gorenstein projective, totally reflexive
