We study, in this article, the FGT-injective dimensions of Π-coherent rings. If R is right Π-
coherent, and TI (resp. TF) stands for the class of FGT-injective (resp. FGT-flat) R-modules …

In this paper we extend the notion of FP-injective modules to that of complexes and
characterize such complexes. We show that some characterizations similar to those for …

In this paper, let $ R $ be a ring and $(\mathcal {F},\mathcal {C}) $ a cotorsion pair of right $
R $-modules. $\mathcal {F} $-dimension ($\mathcal {C} $-dimension) of right $ R $-modules …

In this paper, we introduce and study the concepts of weak n-injective and weak n-flat
modules in terms of super finitely presented modules whose projective dimension is at most …

In this article, the direct and inverse limits of w-modules of a commutative ring R are
discussed. We prove that, if {M i} is a family of w-modules of R, then and are both w …

Let m and n be fixed positive integers and M a right R-module. Recall that M is said to be ($
m $, $ n $)-injective if $ Ext^ 1$(P, M)= 0 for any ($ m $, $ n $)-presented right R-module P; …

Let R be any ring. A right R-module M is called n-copure projective if Ext1 (M, N)= 0 for any
right R-module N with fd (N)≤ n, and M is said to be strongly copure projective if Ext i (M, F) …

Let R be a commutative ring and C a semidualizing R-module. For a non-negative integer n,
we study a natural generalization of copure injective (flat) modules by introducing the …
