G-valued Stokes data: an example, by Mario Garcia-Fernandez.

Abstract: We define Stokes data for an irregular connection on a holomorphic principal bundle. Following "G-bundles, isomonodromy and quantum Weyl groups" (Boalch), we consider the structure group of the bundle to be an arbitrary complex reductive Lie group. We will discuss an example in detail, based on "Gauge Theory and willd ramification" (Witten). Time permitting, isomonodromic deformations of meromorphic connections will be defined.
