Abstract:

Let R be an associative ring with unit 1 ̸= 0, we call an unital left R-module M semi co-Hopfian (resp semi Hopfian ) if any injective (resp. surjective) endomorphism of M has a direct summand image (resp kernel). Starting from that every artinian module is co-Hopfian and so semi co-Hopfian, we showad in this paper that the class of ring on which every semi co-Hopfian module is artinian coincide with the class of artinian principal ideal rings when the v.p is satisfied. Moreover, some properties of this class of rings are given.

Keywords:
