Deformations of free and linear free divisors (1110.0366v3)
Published 3 Oct 2011 in math.AG and math.RT
Abstract: We investigate deformations of free and linear free divisors. We introduce a complex similar to the de Rham complex whose cohomology calculates deformation spaces. This cohomology turns out to be zero for many linear free divisors and to be constructible in many cases
