A Note On Coretractable Modules

H. Q. Dinh, A. K. Singh, A. K. Mahato, S. Sriboonchitta


We discuss the structures of coretractable and mono-coretractable modules. We provide the characterizations of coretractable modules in term of Kasch rings, CS modules, mono-coretractable modules, projective modules, epi-retractable modules and retractable modules. We derive some equivalent conditions related with coretractable and mono-coretractable modules. Among others, some results of coretractable modules in term of symmetric modules are obtained.
