Gorenstein Flat and Projective (Pre)Covers
We consider a right coherent ring R. We prove that the class of Gorenstein ﬂat complexes is covering in the category of complexes of left R-modules Ch(R). When R is also left n-perfect, we prove that the class of Gorenstein protective complexes is special precovering in Ch(R).
