This book collects the scientific contributions of a group of leading experts who took part in the INdAM Meeting held in Cortona in September 2014. With combinatorial techniques as the central theme, it focuses on recent developments in configuration spaces from various perspectives. It also discusses their applications in areas ranging from representation theory, toric geometry and geometric group theory to applied algebraic topology.

Filippo Callegaro was born in 1980. He received a PhD in Mathematics from Scuola Normale Superiore of Pisa under the direction of Mario Salvetti in 2007. In 2008 he was offered a research position at the Scuola Normale. In 2013 he switched to the University of Pisa, where his work focuses on the topology of configuration spaces, cohomology of braid groups and generalizations, hyperplane and toric arrangements.
