| Abstract: |
| In this paper, the concepts of a weakly relative hereditary module, a weakly relative coheredjtary module and a relative hereditary module are introduced . The endomorphism rings of self-hereditary modules are studied. We prove that for P a left self-hereditary modules S=EndR(P) is left semi-hereditary as a ring. |
