Small rational model of subspace complement

Combinatorics 2007-05-23 v2 Algebraic Topology

Abstract

In the paper we compute the ring strucure on the rational cohomology of a complex subspace complement. For that we construct a small differential graded subalgebra of the De Concini-Procesi wonderful model that is quasi isomorphic to this model. For two classes of arrangements explicit presentation of the ring is given.
