Motivic Donaldson-Thomas theory of the conifold

Date: 
Friday 15th April 2011 - 14:30 to 15:30
Venue: 
INI Seminar Room 1
Abstract: 
The talk will explain the computation of the motivic refinement of Donaldson-Thomas theory and related enumerative theories on the resolved conifold geometry, in all chambers of the space of quiver stability conditions. The results are in full agreement with the expected answer from the refined topological vertex of Iqbal-Kozcaz-Vafa, and the wall-crossing computations of Jafferis-Chuang. This is joint work with Andrew Morrison and Kentaro Nagao.
