Neutrosophic projective G-submodules [PDF]

open access: yesNeutrosophic Sets and Systems, 2020
A significant area of module theory is the concept of free modules, projective modules and injective modules. The goal of this study is to characterize the projective G-modules under a single-valued neutrosophic set.

FCP投射模与某些环(FCP-projective modules and some rings)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2010
Let R be a ring. A module MR is called FCP-projective if for every finitely corelated right R-module A. A ring R is called right co-coherent if every finitely cogenerated factor module of a finitely cogenerated injective right R-module is finitely ...

Injective Module [PDF]

open access: yes, 2009
An R-Module Q is injective if for every exact sequence and every R-Module homomorphism lifts to R-Module homomorphism , and also Q is a direct summand of M and every short exact sequence ...

Epis and monos which must be isos

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1984
Orzech [1] has shown that every surjective endomorphism of a noetherian module is an isomorphism. Here we prove analogous results for injective endomorphisms of noetherian injective modules, and the duals of these results.

On injective and divisible modules [PDF]

open access: yesArabian Journal of Mathematics, 2012
The author studies generalizations of injective and divisible modules. For a nonempty collection \(\mathfrak A\) of submodules of an \(R\)-module \(M\), the author defines an \(\mathfrak A\)-\(M\)-injective module and gets a characterization for a submodule \(M\) of a projective module \(P\) to be projective in terms of \(\{M\}\)-\(P\)-injective ...

On subinjectivity domains of RD-injective modules

open access: yes, 2022
The subjectivity domain of a module allows us to evaluate how close (or far) a module is from being injective. In this paper, we consider three families of rings characterized by their RD-injective left R-modules via the subinjective domain: those whose ...

On np-injective rings and Modules

open access: yes, 2023
A given R-module  is called a right np-injective module if for any non-nilpotent element  of , and any right R-homomorphism  can be extended to , if  is np-injective, then  is a right np-injective ring.

Strongly injective modules

open access: yes, 2021
Let R be a ring with identity and M be a left R-module. The module M is called strongly injective if whenever M+ K= N with M? N, there exists a submodule K? of K such that M?K?=N.

On PS-Injective Modules

open access: yesMathematics
In this paper, we introduce the concept of ps-injective modules, which plays a key role in our approach. We develop the various properties of these modules.

Relative injectivity and CS-modules

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
In this paper we show that a direct decomposition of modules M⊕N, with N homologically independent to the injective hull of M, is a CS-module if and only if N is injective relative to M and both of M and N are CS-modules. As an application, we prove that
