w-extending and pw-extending Modules

Abstract

In this work, we introduce and study two concepts of modules. The first one is a generalization of extending modules which is called a w-extending module. And the second concept is called pw-extending module which is a stronger property than w-extending. We give basic properties, example and characterization of these concepts. Moreover relationship of w-extending module and pw-extending modules with other types of modules are studied
