Injective modules over a ring of Krull type

摘要

In this paper, we study codivisorial injective modules over a ring of Krull type. Essentially, we obtain two main results: First, we give a necessary and sufficient condition for a ring of Krull type A to be independent ring of Krull type. Second, we prove that any direct sum of codivisorial injective modules is xi-injective; where xi is a set of some special ideals.
