The ring of endomorphisms of fully stable mooules and vasconcelos problem

الملخص EN

Throughout this paper the ring R is supposed to be commutative with unity and by an R-module we shall mean (a left) R-module.

Full stability of the ring of endomorphisms of a fully stable module is established.

Caracterization of modules in which the ring of endomorphisms of each submodule is commutative is studied.
