Abstract

Following (Kosa̧n in Algebra Colloq. 14:53–60, 2007), a module M is called δ-supplemented if, for every submodule of N of M, there exists LN such that M=N+L and NL δ L. A module M is called δ-lifting if, for any NM, there exists a decomposition M=AB such that AN and NB δ M. In this paper, we study e-supplemented modules and e-lifting modules which are generalized δ-supplemented modules and δ-lifting modules. Some properties of these modules are considered. Moreover, we also have new characterizations of Artinian (resp., Noetherian) Rad e (M) module studied with chain conditions on e-supplemented modules.
