Andreas Hohl - The Fourier transform of Stokes local systems

Abstract: Stokes data encode information about irregular singularities of differential equations, and in general it is a difficult task to describe how they behave under Fourier transform. Building on a recent work of T. Mochizuki and using the language of Stokes local systems of P. Boalch, one obtains an explicit and algorithmic such transformation rule in the case of systems of pure level. In this talk, I will explain the concept of a Stokes local system as well as our algorithm, and I will in particular illustrate it in concrete examples. This is joint work with Jean Douçot.
