... sufficient and necessary conditions of Hopfian and Co-Hopfian modules. In particular, we show that the weakly Co-Hopfian regular module R R is Hopfian, and the left R-module M is Co-Hopfian if and only ... otherwise, ring R is associative and has an identity, M is a left R-module. An essential submodule K of M is denoted by K ≤ e M, and a superfluous submodule L of M is denoted by L ...
