Title:Topology and homotopy of line arrangement

Abstract: In this presentation, we will discuss the relation between the combinatorics, the homotopy and the topology of line arrangement. In particular, we will prove that, for a fixed combinatorics (ie an intersection lattice), the topology of an arrangement is not determined by the homotopy type of its complement.
