DESCRIPTION:Classical Hodge theory says that the sheaves of ex
 terior\ndifferentials control the usual Betti coho
 mology of a smooth complex\nprojective variety X. 
 Is there a similar relation between the sheaves of
 \nsymmetric differentials and the topology of X? I
 n this talk I will explain\nhow symmetric differen
 tials control finite dimensional representations o
 f\nthe topological fundamental group of X. Using a
 utomorphic forms this leads\nto new striking rigid
 ity properties for fundamental groups of certain b
 all\nquotients.
