Maximal $d$-spectra via Priestley duality

General Topology 2025-12-01 v2

Abstract

We use Priestley duality as a new tool to study maximal dd-spectra of arithmetic frames, both with and without units. We pay special attention to when the maximal dd-spectrum is compact or Hausdorff. Various necessary and sufficient conditions are given, including a construction of an arithmetic frame with a unit whose maximal dd-spectrum is not Hausdorff, thus resolving an open problem in the literature.
