In this paper, several characterizations of semi-compact modules are given. Among other
results, we study rings whose semi-compact modules are injective. We introduce the …

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 …

Let R be a ring and U a left R-module with S= End (RU). The aim of this paper is to
characterize when S is coherent. We first show that a left R-module F is TU-flat if and only if …

In this paper, we continue to study and investigate the homological objects related to s-pure
and neat exact sequences of modules and module homomorphisms. A right module A is …

Let R be a ring. A left R-module M is called strongly max-flat if for every simple right R-
module S and every i≥ 1. In this article, we show that the class of strongly max-flat R …

The aim of this paper is to characterize multiplicative subsets S and commutative rings R for
which every R-module is strongly flat with respect to S. Commutative rings R for which all R …

In this paper, we study left orthogonal class of max-flat modules which are the homological
objects related to s-pure exact sequences of modules and module homomorphisms …

Let R, S be arbitrary associative rings and RCS a semidualizing bimodule. We give some
equivalent characterizations for R being left coherent (and right perfect) rings, left …

P. VAMOS [11] has defned and studied'finitely embedded modules' as the dual of'finitely
generated modules'. JANS [4] called them as co finitely generated modules and defined a …
