Some Remarks on Gorenstein Projective Precovers

Abstract: In this paper, we prove that for a $n$-perfect ring $R$ various classes of relative Gorenstein projective $R$-modules are special precovering, among them including the Gorenstein projectives and Ding projectives. Also we prove that the class of projectively coresolved Gorenstein flat $\mathcal{PGF} (R)$ fulfils the same feature. We also introduce a new class of Gorenstein projective $R$-modules relative to the Auslander class $\mathcal{A} _{C} (R)$ of a semidualizing $(R,S)$-bimodule $_R C_S$.
