Abstract

 

In this note we show that given two complete geodesic Gromov hyperbolic spaces that are roughly isometric and an arbitrary ϵ>0 (not necessarily small), either the uniformization of both spaces with parameter ϵ results in uniform domains, or else neither uniformized space is a uniform domain. The terminology of "uniformization" is from [BHK], where it is shown that the uniformization, with parameter ϵ>0, of a complete geodesic Gromov hyperbolic space results in a uniform domain provided ϵ is small enough.
