Abstract
We introduce the notion of weak π-extending modules which is a proper generalization of π-extending and weak CS-modules. Several characterizations and connections between weak π-extending modules and related concepts are obtained. Direct sums and direct summand properties are also provided. Moreover, we investigate when the former class has an indecomposable decomposition and exchange properties.
