Classical Hodge theory says that the sheaves of exterior
differentials control the usual Betti cohomology of a smooth complex
projective variety X. Is there a similar relation between the sheaves of
symmetric differentials and the topology of X? In this talk I will explain
how symmetric differentials control finite dimensional representations of
the topological fundamental group of X. Using automorphic forms this leads
to new striking rigidity properties for fundamental groups of certain ball
quotients.
