Surface group representations in non-compact groups of Hermitian type have many nice properties and they have been widely studied from many different points of view. We use Higgs bundles to study the case of representations in the non-compact dual of the special orthogonal group and, in particular, prove rigidity and connectedness results for the moduli space of maximal representations. Along the way we shall compare our results with those for other groups, especially the real symplectic group.


The talk is based on joint work with Steve Bradlow and Oscar Garcia-Prada.
