In this paper, we introduce a general form of pseudo-p-injectivity. Let be a right-module
and=(), its endomorphism ring. A right-module is called a generalized-pseudo-Mp-injective …

If R is an integral domain, let be the class of torsion free completely decomposable R-
modules of finite rank. Denote by the class of those torsion-free R-modules A such that A is …

Let R be a ring. A right R-module A is said to be C-flat if the kernel of any epimorphism B→ A
is C-pure in B, ie the induced map Hom (C, B)→ Hom (C, A) is surjective for any cyclic right …

A ring extension is a ring homomorphism preserving identities. In this article, we establish
the relationship among relatively flat modules, relatively projective modules and relatively …

We introduce the notion of almost pseudo-injective modules (AP-injective modules), which
generalizes the idea of pseudo-injective and almost injective modules. In support, we …

In this thesis, we conducted a comprehensive study of neat-subgroups of abelian groups. In
this context, we investigated exact sequences, injectivity, projectivity, essential extensions …

We study direct-sum decompositions of RD-projective modules. In particular, we investigate
the rings over which every RD-projective right module is a direct sum of cyclically presented …

A morphism f: M→ N of left R-modules is a phantom morphism if for any morphism g: A→ M,
with A finitely presented, the composition fg factors through a projective module …
