BPS states, Donaldson-Thomas invariants and Hitchin pairs
Seminar Room 1, Newton Institute
AbstractA 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.
