Formality of the complements of subspace arrangements with geometric lattices

Eva Maria Feichtner, Sergey Yuzvinsky

Published 2005-04-15Version 1

We show that, for an arrangement of subspaces in a complex vector space with geometric intersection lattice, the complement of the arrangement is formal. We prove that the Morgan rational model for such an arrangement complement is formal as a differential graded algebra.
