In this article, we characterize some rings in terms of the DG-projective, injective and flat
complexes. We also give some connections between DG-injective complexes and DG-flat …

This is a study of Ding projective modules relative to a semidualizing module and related
topics. Firstly, we study DC-projective dimensions and DC-projective modules under change …

A right R-module M is called a D 3-module, if M 1 and M 2 are direct summands of M with M=
M 1+ M 2, then M 1∩ M 2 is a direct summand of M. Following the work of Bass on projective …

Let R be an arbitrary ring. We introduce and study a generalization of injective and flat
complexes of modules, called weak injective and weak flat complexes of modules …

Several papers find conditions on a ring R in order for certain properties of modules to be
preserved under direct sums, and direct products. Thus we know when direct sums of …

We say that a ring R is a right RDV-ring if each simple right R-module is RD-injective. In this
paper, we study the notion of RDV-rings which is a non-trivial generalization of V-rings and …

In this paper, we introduce the notion of DP-projective modules. It is shown that a left R-
module M over a ring R is DP-projective if and only if it is a cokernel of a Ding projective …

It is proven that every commutative ring whose RD-injective modules are Σ-RD-injective is
the product of a pure semisimple ring and a finite ring. A complete characterization of …
