D-modules and Singularities

Scope of the special session

The goal of this session is to present a significant part of the current research in the relation between the theories of D-modules and of singularities. These theories have seen a remarkable increase in the number of publications in the last years. Among other topics, in this session there will be talks about: 1) Singularities and hyperplane arrangements, 2) Arithmetic D-modules and p-adic cohomology, 3) The Riemann-Hilbert problem for holonomic D-modules, 4) Singularities of hypergeometric D-modules, 5) Asymptotic developments of solutions of differential systems, and 6) Perverse sheaves and representation theory.
