in this paper we introduce the notions of g∗l-module and g∗l-module whichare two proper generalizations of δ-lifting modules. we give some characteriza tions and properties of these modules. we show that a g∗l-module decomposesinto a semisimple submodule m1 and a submodule m2 of m such that every non-zero submodule of m2 contains a non-zero δ-cosingular submodule.
We will study modules whose cofinite submodules have weak generalized-$\delta$-supplements. We attempt to investigate some properties of cofinitely weak generalized $\delta$-supplemented modules. We will prove for a module $M$ and a semi-$\delta$-hollow submodule $N$ of $M$ that,
In this paper we introduce Goldie$^{\ast }$-$\delta $-supplemented modules as follows. A module $M$ is called Goldie$^{\ast }$-$\delta $-supplemented (briefly, G$_{\delta }^{\ast }$-supplemented) if there exists a $\delta $-supplement $T$ of $M$ for every submodule $A$ of $M$ suc
We introduce the concepts of lifting modules and (quasi-)discrete modules relative to a given left module. We also introduce the notion of SSRS-modules. It is shown that (1) if M is an amply supplementedmodule and 0→N ′ →N →N ′′ → 0 an exact sequence, then M isN-lifting if and on
In this paper we introduce the concept of $tCC$-modu\-les which is a proper generalizationof ($t$-)lifting modules. Let $M$ be a module over a ring $R$.We call $M$ a $tCC$-module(related to $t$-coclosed submodules) provided that for every$t$-coclosed submodule $N$ of $M$, there e
