Retractable and coretractable modules
AN Abyzov, AA Tuganbaev - Journal of Mathematical Sciences, 2016 - Springer
In this paper, we study mod-retractable modules, CSL-modules, fully Kasch modules, and
their interrelations. Right fully Kasch rings are described. It is proved that for a module M of …

[PDF][PDF] A generalization of coretractable modules
AR Moniri Hamzekolaee - Journal of Algebraic Systems, 2018 - jas.shahroodut.ac.ir
Let $ R $ be a ring and $ M $ a right $ R $-module. We call $ M $, coretractable relative to
$\overline {Z}(M) $(for short, $\overline {Z}(M) $-coretractable) provided that, for every proper …

Iso-retractable modules and rings
AK Chaturvedi - Asian-European Journal of Mathematics, 2019 - World Scientific
The modules which are isomorphic to their non-zero submodules are known as iso-
retractable. We characterize simple modules in terms of iso-retractable modules. We provide …

Coretractable modules
B Amini, M Ershad, H Sharif - Journal of the Australian Mathematical …, 2009 - cambridge.org
An R-module M is called coretractable if HomR (M/K, M)≠ 0 for any proper submodule K of
M. In this paper we study coretractable modules and their endomorphism rings. It turns out …

Kasch modules
T Albu, R Wisbauer - Advances in Ring Theory, 1997 - Springer
An associative ring R is a left Kasch ring if it contains a copy of every simple left R-module.
Transferring this notion to modules we call a left R-module M a Kasch module if it contains a …

Fully Kasch modules and rings
We carry out a study of modules MR satisfying the property that every module in σ [M] is a
Kasch module. Such modules are called fully Kasch. Several sufficient conditions for a …
