A principal ideal theorem for compact sets of rank one valuation rings

Abstract

Let FF be a field, and let Zar(F)(F) be the space of valuation rings of FF with respect to the Zariski topology. We prove that if XX is a quasicompact set of rank one valuation rings in Zar(F)(F) whose maximal ideals do not intersect to 00, then the intersection of the rings in XX is an integral domain with quotient field FF such that every finitely generated ideal is a principal ideal. To prove this result, we develop a duality between (a) quasicompact sets of rank one valuation rings whose maximal ideals do not intersect to 00, and (b) one-dimensional Pr\"ufer domains with nonzero Jacobson radical and quotient field FF. The necessary restriction in all these cases to collections of valuation rings whose maximal ideals do not intersect to 00 is motivated by settings in which the valuation rings considered all dominate a given local ring.
