Coset topologies on $\mathbb{Z}$ and arithmetic applications

Number Theory 2022-11-28 v3 General Topology

Abstract

We provide a construction which covers as special cases many of the topologies on integers one can find in the literature. Moreover, our analysis of the Golomb and Kirch topologies inserts them in a family of connected, Hausdorff topologies on Z\mathbb{Z}, obtained from closed sets of the profinite completion Z^\hat{\mathbb{Z}}. We also discuss various applications to number theory.
