DESCRIPTION:A toric arrangement is given by a family A of level sets of characters of a complex torus T. \nThe study of these objects is a fairly recent topic at the crossroads of combinatorics, topology and algebra. \n<br>\nThe focus of this talk will be on the topology of the complement M:=T \ A, and in particular \non the extent to which it is determined by the combinatorial data of the arrangement A. \n<br>\nAfter an introduction to toric arrangements and a review of known results, I will present \nsome recent joint work with Giacomo d'Antonio, focusing on the fundamental group of M \nand on the proof that M is a minimal space (and thus homologically torsion-free).
