Supplemented modules and⊕-supplemented modules are useful in characterizing
semiperfect modules and rings. Recently, the notion of cofinitely supplemented modules and …

In this work, we prove that an R-module M is cofinitely δ-supplemented (ie each cofinite
submodule of M has a δ-supplement) if and only if every maximal submodule of M has a δ …

In this paper we introduce generalized f-semiperfect modules as a generalization of the
generalized semiperfect modules. We give various properties of the generalized f …

Let R be an arbitrary ring with identity and M a right R-module. In this paper, we introduce a
class of modules which is an analogous to δsupplemented modules and principally⊕ …

Let R be a ring and M a right R-module. M is called⊕-cofinitely supplemented if every
submodule N of M with M/N finitely generated has a supplement that is a direct summand of …

Let R be a ring with Jacobson radical J (R). Following CNI, a submodule N of a left R-
module RM is said to lie over a summand of M if there exists an idempotent e E End (RM) …

Let R be an arbitrary ring with identity and M a right R-module. In this paper, we introduce a
class of modules which is an analogous of δ-supplemented modules defined by Kosan. The …

In the present paper, we define generalized (amply) cofinitely supplemented modules, and
generalized⊕-cofinitely supplemented modules are defined as a generalization of (amply) …

Let $ R $ be a ring and $ M $ a right $ R $-module. $ M $ is called $\oplus $-cofinitely
supplemented if every submodule $ N $ of $ M $ with $\frac {M}{N} $ finitely generated has a …
