Cohomology rings of compactifications of toric arrangements

Abstract

Some projective wonderful models for the complement of a toric arrangement in a n-dimensional algebraic torus T were constructed in [3]. In this paper we describe their integer cohomology rings by generators and relations.

A new section (Section 9) has been added, to include the presentation of the cohomology rings of all the strata in the boundary
