Chamber basis of the Orlik-Solomon algebra and Aomoto complex

Geometric Topology 2009-11-13 v1 Combinatorics

Abstract

We introduce a basis of the Orlik-Solomon algebra labeled by chambers, so called chamber basis. We consider structure constants of the Orlik-Solomon algebra with respect to the chamber basis and prove that these structure constants recover D. Cohen's minimal complex from the Aomoto complex.
