Abstract

In this work, we extend the notion of retractability to  s- retractability. An R-module is called s-retractable if  for all nonzero . Also we extend coretractable modules to semi-coretractable modules. An R-module  is called semi-coretractable if  for all maximal essential submodule  of . We investigate theseclasses of modules and extend some of main theorems on retractable and coretractable modules to s-retractable and semi-coretractable modules, respectively.
