Abstract

In this paper we are mainly concerned with DW rings, i.e., rings

in which every ideal is a w-ideal. We give some new classes of DW rings and we

show how the concept of DW domains is used to characterize Prufer domains

and Dedekind domains. Namely, we prove that a ring is a Prufer domain

(resp., Dedekind domain) if and only if it a coherent (resp., Noetherian) DW

domain with nite weak global dimension.

Keywords

DW ring and domain, PvMD, Krull domain
