Representations of surface groups and Higgs bundles Prof. Oscar Garcia-Prada CSIC, Madrid. 24-01-06 Abstract Let X be a compact Riemann surface and G be a connected semisimple Lie group. Using Higgs bundle theory, we count components of the moduli space of representations of the fundamental group of X in G, when G is the group of isometries of a non-compact Hermitian symmetric space.
