Let A be an abelian category. For a pair (X, Y) of classes of objects in A, we define the weak
and the (X, Y)-Gorenstein relative projective objects in A. We point out that such objects …

We investigate the relative and Tate cohomology theories with respect to Ding modules and
complexes, consider their relations with classical and Gorenstein cohomology theories. As …

In this paper, we introduce the notion of DP-projective modules. It is shown that a left R-
module M over a ring R is DP-projective if and only if it is a cokernel of a Ding projective …

For two classes of right R-modules W, X such that P⊂ W⊂ X, where P is the class of
projective right R-modules, we show that there is an Avramov–Martsinkovsky type exact …
