Presented by:

Venue: 
INI Seminar Room 1
Abstract: 
A string theoretic construction will be presented relating BPS states, Donaldson-Thomas invariants and the cohomology of the Hitchin system. In particular, the work of Hausel and Rodrgiguez-Villegas will be given a natural physical explanation based on geometric engineering.

This is work in collaboration with Wu-yen Chuang and Guang Pan.
