Gorenstein injective, projective and flat (pre)covers

2014
Summary: We prove that if the ring \(R\) is left noetherian and if the class \(\mathcal {GI}\) of Gorenstein injective modules is closed under filtrations, then \(\mathcal {GI}\) is precovering. We extend this result to the category of complexes. We also prove that when \(R\) is commutative noetherian and such that the character modules of Gorenstein ...
