Let $ R $ be a ring and $ M $ be a left $ R $-module. $ M $ is called generalized $\oplus $-
supplemented if every submodule of $ M $ has a generalized supplement that is a direct …

Let R be a ring and M a right R-module. M is called⌖-supplemented if every submodule of M
has a supplement that is a direct summand of M, and M is called completely⌖-supplemented …

Let R be a ring and. M be a left R-module. M is called generalized circle plus-supplemented
if every submodule of M has a generalized supplement that is a direct summandof M. In this …

Let R be a ring and M a right R-module. M is called--δ⊕ supplemented, if every submodule
of M has a-δ supplemented that is a direct summand of M. In this paper, several properties of …

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 …

A module M is⊕‐supplemented if every submodule of M has a supplement which is a direct
summand of M. In this paper, we show that a quotient of a⊕‐supplemented module is not in …

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⊕ …

We investigate the structure of rings over which every finitely generated δ-supplemented
module is supplemented. Some characterizations of this type of rings are given. We …

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 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 …
