D Branes and Phases on String Worldsheet
arXiv:hep-th/0404101 · doi:10.1016/j.nuclphysb.2004.08.036
Abstract
We generalize the worldsheet derivation of the topological open/closed string duality given in hep-th/0205297 to cases when there are different types of D branes on the open string side. We use the mirror Landau-Ginzburg description to clarify the correspondence between D branes on the open string side and C phases on the closed string side. We also discuss the duality from the point of view of the B model.
