Resolving rational cohomological dimension via a Cantor group action

Geometric Topology 2015-09-30 v1 General Topology

Abstract

By a Cantor group we mean a topological group homeomorphic to the Cantor set. We show that a compact metric space of rational cohomological dimension nn can be obtained as the orbit space of a Cantor group action on a metric compact space of covering dimension nn. Moreover, the action can be assumed to be free if n=1n=1.
