In this paper we develop an axiomatic approach to coarse homology theories.
We prove a uniqueness result concerning coarse homology theories on the
category of `coarse CW-complexes'. This uniqueness result is used to prove a
version of the coarse Baum-Connes conjecture for such spaces.Comment: Published by Algebraic and Geometric Topology at
