Abstract
It is well-known that a paracompact space X is of covering dimension at most n if and only if any map f:X→K from X to a simplicial complex K can be pushed into its n-skeleton K(n). We use the same idea to characterize asymptotic dimension in the coarse category of arbitrary coarse spaces. Continuity of the map f is replaced by variation of f on elements of a uniformly bounded cover. In the same way, one can generalize Property A of G. Yu to arbitrary coarse spaces.
