Let R be a ring and n be a non-negative integer. In this paper, we introduce and study the
notions of Gorenstein n-weak injective and Gorenstein n-weak flat modules by using the …

Let R be a ring and n, k be two non-negative integers. As an extension of several known
notions, we introduce and study (n, k)-weak cotorsion modules using the class of right R …

Let R be an associative ring and let n be a non-negative integer. In this paper, we consider n-
super finitely presented, Gorenstein n-weak injective and Gorenstein n-weak flat modules …
