Title: D-Brane Superpotentials: A Worldsheet Perspective
Date (JST): Mon, Nov 15, 2010, 14:00 - 17:00
Place: Seminar Room A
Abstract: We explain how superpotentials in topological string theory can be obtained with worldsheet methods. On the one hand, from the worldsheet perspective the superpotential of a D-brane wrapping internal cycles of a Calabi-Yau manifold is given as a generating functional for disk correlation functions. On the other hand, from the geometric point of view D-brane superpotentials are captured by certain chain integrals. We present recent results which show how these two approaches are related. In particular we show how worldsheet correlators in Landau-Ginzburg theories computed in the matrix factorizations description can be retrieved from relative period integrals.
