Gauge Theory and the Geometric Langlands Program


These talks will discuss how electric-magnetic duality of four-dimensional gauge theory can be used to describe the geometric Langlands Program. The Associated two-dimensional picture is mirror symmetry of the moduli space of Higgs bundles. The 't Hooft operators of gauge theory become the geometric Hecke operators of the geometric Langlands program, and the basic statements about these operators come from electric-magnetic duality applied to Wilson and 't Hooft operators. Ramified flat bundles are incorporated by allowing impurities in the four-dimensional gauge theory that are supported on a submanifold of codimension two.
