Rings with finite n-Weak injective dimension and (n,k)-Weak cotorsion modules
Mostafa Amini, Houda Amzil, Driss Bennis
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-modul…

Category of n-weak injective and n-weak flat modules with respect to special super presented modules
Mostafa Amini, Houda Amzil, Driss Bennis
Let be a ring and , two non-negative integers. In this paper, we introduce the concepts of -weak injective and -weak flat modules and via the notion of special sup…
