A realization theorem for almost Dedekind domains

Abstract

An integral domain DD is called an SP-domain if every ideal is a product of radical ideals. Such domains are always almost Dedekind domains, but not every almost Dedekind domain is an SP-domain. The SP-rank of DD provides a natural measure of the deviation of DD from being an SP-domain. In the present paper we show that every ordinal number α\alpha can be realized as the SP-rank of an almost Dedekind domain.
