Resumen de Injective Modules over Strong Mori Domains

H. Kim, E.S. Kim, Y. S. Park

• We show that an integral domain R is a strong Mori domain if and only if any direct sum of co-semi-divisorial injective R-modules is injective. We also show that if M is a nonzero co-semi-divisorial torsion module over a strong Mori domain R with w-dim(R)=1, then the semi-divisorial envelope of M is isomorphic to the direct sum of M localized at P, where P runs over the set of w-maximal ideals of R.
