Abstract
Let be a left module over a ring and an ideal of . is called an -supplemented module (finitely -supplemented module) if for every submodule (finitely generated submodule) of , there is a submodule of such that , and is PSD in . This definition generalizes supplemented modules and -supplemented modules. We characterize -semiregular, -semiperfect and -perfect rings which are defined by Yousif and Zhou [15] using -supplemented modules. Some well known results are obtained as corollaries.
