… a generalization of coretractable modules. An … -module M is called coretractable if
HomR(M/N,M) = 0, for any proper submodule N of M. For more information about coretractable …

… of biretractable modules over Dedekind domains is fully determined. It is proved that the
right R-module R R is biretractable if and only if R has a unique simple right R-module (up to …

… prove that when two concepts coretractable and δ(M)coretractable coincide. Among them, …
or it is a coretractable module, then M is coretractable if and only if M is δ(M)-coretractable. We …

… of Co-retractable module and related to other classes of modules such as multiplication module,
… As an example of not Co-retractable module, we present the rational numbers Q and the …

… prove that when two concepts coretractable and δ(M)coretractable coincide. Among them, …
or it is a coretractable module, then M is coretractable if and only if M is δ(M)-coretractable. We …

… In this short note, we study retractable modules and coretractable modules in the categories
\(\sigma [M]\), and the retractability, coretractability of comodules over coalgebras. In …

… However they are coincide in the class of nonsingular module (5)". In(6), Hadi … coretractable
modules which are essentially coretractable and weakly essentially coretractable modules, …

… CC-ring if each left R-module is coretractable. CC-rings were … classes of retractable and
coretractable modules over the ring of … of retractable and coretractable modules carry over in an …

… Moreover retractable modules, compressible modules, and some … , a coretractable module
in [8]. However, Amini [6] studied this class of modules, where M is called coretractable if for …

… Clearly, every coretractable module is a CFR module but the converse is not true. For example,
… Thus R R is not a coretractable module but it is CFR, by part (1). Also, see Corollary 2.10. …
