This new class of modules properly contains the class of extending modules. It is well known that the class of extending modules is closed under direct summands, but not under direct sums. In contrast to extending (or CS) modules, it is shown that the class of modules with former property is closed under direct sums. However we provide number of algebraic topological examples which show that this new class of modules is not closed under direct summands. To this end we obtain several results on the inheritance of the latter closure property.eninfo:eu-repo/semantics/closedAccessMathematicsC-11-moduleComplement submoduleExtending moduleZ-closed submoduleModulesArticle0004300442000212-s2.0-8503807161230713078467MathematicsInjective Module; Artinian Ring; Ring
