Place: Seminar Room A
Abstract: In the first talk I give an overwiev on how one can use Landau-Ginzburg models to compute correlation functions for intersecting D-branes. Via mirror symmetry this amounts to count triangle-shaped instantons that bound several D-branes. The second talk is more specialized and discusses deformations of the LG model and the differential equations that determine the correlation functions.
