An isomorphism between models of graphic arrangements
Giovanni Gaiffi, Oscar Papini, Viola Siconolfi
This paper presents a bridge between the theories of wonderful models associated with toric arrangements and wonderful models associated with hyperplane arrangements. In a previous…
A basis for the cohomology of compact models of toric arrangements
Giovanni Gaiffi, Oscar Papini, Viola Siconolfi
In this paper we find monomial bases for the integer cohomology rings of compact wonderful models of toric arrangements. In the description of the monomials various combinatorial o…
A differential algebra and the homotopy type of the complement of a toric arrangement
Corrado De Concini, Giovanni Gaiffi
We show that the rational homotopy type of the complement of a toric arrangement is completely determined by two sets of combinatorial data. This is obtained by introducing a diffe…
Wonderful models for generalized Dowling arrangements
Giovanni Gaiffi, Viola Siconolfi
For any triple given by a positive integer n, a finite group G, and a faithful representation V of G, one can describe a subspace arrangement whose intersection lattice is a genera…
Cohomology rings of compactifications of toric arrangements
Corrado De Concini, Giovanni Gaiffi
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 coh…
Projective Wonderful Models for Toric Arrangements
Corrado De Concini, Giovanni Gaiffi
In this paper we illustrate an algorithmic procedure which allows to build projective wonderful models for the complement of a toric arrangement in a n-dimensional algebraic torus…
