characteristic classes of flat symplectic bundles
abstract:
i'll explain kontsevich's approach, using gelfand-fuchs cohomology, to constructing characteristic classes of flat symplectic bundles. this can be used to talk about rozansky-witten invariants of holomorphic symplectic manifolds and construct cohomology classes on the moduli space of curves.
