Boundness in almost Dedekind domains

Commutative Algebra 2023-01-25 v1

Abstract

We study different form of boundness for ideals of almost Dedekind domains, generalizing the notions of critical ideals, radical factorization, and SP-domains. We show that every almost Dedekind domain has at least one noncritical maximal ideals and, indeed, the set of noncritical maximal ideals is dense in the maximal space, with respect to the constructible topology; as a consequence, we show that every almost Dedekind domain is SP-scattered, and in particular that the group Inv(D)\mathrm{Inv}(D) of invertible ideals of an almost Dedekind domain DD is always free. If DD is an almost Dedekind domain with nonzero Jacobson radical, we also show that there is at least one element whose ideal function is bounded.
