Linearly ordered coarse spaces

General Topology 2021-10-05 v1

Abstract

A coarse space XX, endowed with a linear order compatible with the coarse structure of XX, is called linearly ordered. We prove that every linearly ordered coarse space XX is locally convex and the asymptotic dimension of XX is either 00 or 11. If XX is metrizable then the family of all right bounded subsets of XX has a selector.
