Research Abstract

We investigate coarse geometric properties of unbounded metric spaces that contains asymptotic dimension, colorings for maps, and topological properties of remainders of Higson and Smirnov compactifications. We prove that all proper CAT(0) spaces that are homeomorphic to the plane have asymptotic 2-dimension. This result is the first one step of the solution of a question "Does every CAT(0) group have finite asymptotic dimension?".
