Weakening the notion of R-projectivity, a right R-module M is called max-projective provided
that each homomorphism f: M→ R/I, where I is any maximal right ideal, factors through the …

Recently, the rings whose injective right modules are R-projective (respectively, max-
projective) were investigated and studied in [2]. Such ring are called right almost-QF …

Following, a ring R is called right almost-perfect if every flat right R-module is projective
relative to R. In this article, we continue the study of these rings and will find some new …

A right $ R $-module $ M $ is called $ R $-projective provided that it is projective relative to
the right $ R $-module $ R_ {R} $. This paper deals with the rings whose all nonsingular …

All rings in this work are right ring and all modules is right module (mod) X over a ring R. A
mod X is said to be nearly maximal projective (for short; Ner. Mx. Pro. Mod)) if∀ …

Abstract A right R-module M is called R-projective provided that it is projective relative to the
right R-module R R. One of the parts of this thesis deals with the rings whose all nonsingular …

Let C be a class of modules. We introduce the notion of C¯-extensions. For any modules A
and B, we show that, if C lies in the left part of a balanced pair, then there is a bijection …
