Endomorphism Rings Of Modules

The objective of this paper is to continue our study for a right 1 I - rings and to generalize the concept of 1 I - rings to modules. We call a ring R a right 1 I - ring if every right annihilator for any element of R contains a nonzero idempotent.

a - Small and S - Large Submodules

Our main goal in this research is to find the conditions which make the a - small submodules are equivalent with small submodules and so s- large submodules with large submodules, then find the relatio -nship between the radical of module and the a - small submodules.
