Co-Hopfian Modules
F. C. Leary
If is a commutative ring with , then a co-Hopfian -module is necessarily a module of fractions over a ring of fractions. For commutative Noetherian, we use Matlis…

Hopfian and co-Hopfian modules over Artinian rings
F. C. Leary
An -module is Hopfian (co-Hopfian) if any epic (monic) endomorphism of is an automorphism. If is commutative Noetherian, we characterize the co-Hopfian injective …
