Description

This workshop will be part of MSRI's Special Semester in Hyperplane Arrangements and Applications. The topology of hyperplane arrangements involves a wide range of algebraic and combinatorial as well as topological methods. The main applications are to generalized hypergeometric functions, Knizhnik-Zamolodchikov equations, topology of configuration spaces, and representations of braid and artin groups. This workshop will focus on these and other topics, including homotopy type and fundamental groups, higher homotopy groups, cohomology support loci (resonance and characteristic varieties), Milnor fibers, cohomology of artin groups, braids and configuration spaces, Gauss-Manin connections, KZ and qKZ equations.
