DESCRIPTION:Speaker: Nigel Hitchin\, University of Oxford\nhosted by Tamas
Hausel\nAbstract: The moduli space of Higgs bundles over a Riemann surface
has the structure of a completely integrable Hamiltonian system now known
as the Hitchin system. The critical locus consists of the points at which
the Hamiltonian vector fields become linearly independent. There is a wel
l established general concept of nondegeneracy for such points and under
those conditions one obtains integrable systems of lower dimension. The ta
lk will first focus on applying these methods to the above system and then
discuss topological aspects of the moduli space which are realized by cri
tical loci.
