چکیده

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 φ : c → m such that c is finitely generated and the projective dimension of ker φ is finite and φ is surjective.
