# BPS states, Donaldson-Thomas invariants and the Hitchin system

Friday, November 11, 2011 -

4:00pm to 5:00pm

This talk will report on joint work with Wu-yen Chuang and Guang Pan relating the cohomology of the Hitchin system to Donaldson-Thomas theory and BPS inavariants of Calabi-Yau threefolds. A string-theoretic construction will be presented which relates refined curve-counting invariants to the work of Hausel and Rodriguez-Villegas on character varieties.
