Coarse homotopy on metric spaces and their corona

Comment.Math.Univ.Carolin. 62,2 (2021) 243-257.

Abstract: This paper discusses properties of the Higson corona by means of a quotient on coarse ultrafilters on a proper metric space. We use this description to show that the corona functor is faithful and reflects isomorphisms.

Keywords: Higson corona; coarse geometry
