| Abstract: | This paper mainly uses fpn^- injective right R- modules to investigate fpn^- injective covers, gives a characterization of the existences of monomorphie fpn^- injeetive covers of right R- modules,and proves that every R- module M has a monomorphie fpn^- injective cover φ：E→M M if and only if R is a right fpn^- hereditary ring. |
