In this paper, we give some characterizations of FP-grinjective R-modules and graded right
R-modules of FP-gr-injective dimension at most n. We study the existence of FP-gr-injective …

In this paper, we extend the notions of n-FP-injective and n-flat modules to that of complexes
which we call n-FP-injective and n-flat complexes, respectively and we show that the class of …

In this paper, we extend the notion of C-injective module to that of C-FP-injective module,
where S CR is a semidualizing bimodule over associative rings. We first obtain a result on …

Let R be a ring with identity. RM Thrall defined a QF-3 algebra in [3] and many authors
defined QF-3 rings and studied them (cf.[10]). R is called right QF-3 if R has a minimal a …

Let XX be an extension-closed subcategory of a triangulated category such that XX admits a
weak-cogenerator W W. We investigate finite resolutions by objects in XX and X X-resolution …

In this paper, it is shown that any non-M-cosingular ⊕-supplemented module M is (D_3) if
and only if M has the summand intersection property. Let N∈σM be any module such that …

Let and be two corings over a ring A and be a morphism of corings. We investigate the
situation when the associated induced (“corestriction of scalars”) functor ℳ→ ℳ is a …

Let A and B be associative rings with unit, Mod-A and Mod-B categories of unital right A-
modules and unital right B-modules respectively. For an AB-bimodule* UB, we consider two …
