الملخص الإنجليزي

Let M be an R-module with endomorphism ring S.

The module M is called quasi-principally injective, if every R-homomorphism from Mcyclic submodule K of M to M can be extended to an endomorphism of M.

An R-module N is called M-mininjective, if every R-homomorphism from simple M-cyclic submodule L of M to N can be extended to an Rhomomorphism from M to N.

An R-module M is called quasimininjective , if it is M-mininjective .

An R-module N is called Mprincipally projective, if every R-homomorphism from N to M-cyclic submodule K of M can be lifted to an R-homomorphism from N to M.

These concepts were studied by Chotchaisthit and Wongwai.

In this work, we introduce the notion of principally M-pseudo injective ,Msimple injective, simple M-projective, M-minprojective and we study quasi principally projective modules and M-mininjective .

We give the detail of proofs of known results, supply some examples, and add new results.
