Description
D-branes on Calabi-Yau manifolds can be described by matrix factorizations at the Landau-Ginzburg (LG) point. In this talk I will discuss methods for the study of D-brane moduli spaces and superpotentials within this framework. An emphasis will be put on non-toric complex structure deformations, which arise as bulk moduli from twisted sectors in the LG orbifold. I will outline how the contributions to the effective superpotential from these fields can be computed by considering appropriate defects in the unonrbifolded LG model.
