Minimality of toric arrangements
Giacomo d'Antonio, Emanuele Delucchi
We prove that the complement of a toric arrangement has the homotopy type of a minimal CW complex. As a corollary we obtain that the integer cohomology of these spaces is torsion f…

A Salvetti complex for Toric Arrangements and its fundamental group
Giacomo d'Antonio, Emanuele Delucchi
We describe a combinatorial model for the complement of a complexified toric arrangement by using nerves of acyclic categories. This generalizes recent work of Moci and Settepanell…
