BPS states, Donaldson-Thomas invariants, and Hitchin pairs

Tuesday 15th March 2011 - 10:00 to 11:00
This is a report on recent work in collaboration with Wu-yen Chuang and Guang Pan relating Donaldson-Thomas theory and BPS to the cohomology of the Hitchin system. A string theoretic construction will be presented establishing a connection between curve counting invariants and the work of Hausel and Rodriguez-Villegas. A generalization to parabolic Hitchin pairs will be also briefly discussed.
