Rings with finite n-Weak injective dimension and (n,k)-Weak cotorsion modules

Published 2 May 2021 in math.AC | (2105.00413v2)

Abstract: 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-modules with n-weak flat dimensions at most k. Various examples and applications are also given.
