Abstract

We study the Geometric Langlands Conjecture (GLC) for rank two flat bundles on the projective line CC with tame ramification at five points {p1,p2,p3,p4,p5}\{p_{1}, p_{2}, p_{3}, p_{4}, p_{5} \}. In particular we construct the automorphic DD-modules predicted by GLC on the moduli space of rank two parabolic bundles on (C,{p1,p2,p3,p4,p5})(C, \{p_{1}, p_{2}, p_{3}, p_{4}, p_{5} \}). The construction uses non-abelian Hodge theory and a Fourier-Mukai transform along the fibers of the Hitchin fibration to reduce the problem to one in classical projective geometry on the intersection of two quadrics in P4\mathbb{P}^{4}.
