Prof. Mario Salvetti (Pisa): Some topological results on Configuration Spaces obtained by combinatorial methods

Academic or specialist Colloquium / Congress / Forum

Classical Configuration Spaces of $n$- distinct points in $\mathbb C$ can be generalized in many ways.Here we are mainly interested to Configuration Spaces associated to Artin groups: we show how the cohomology of these spaces is strongly related to well-known combinatorial objects which are defined independently. The "new" tool that we use is a discrete variant of Morse Theory.
