摘要： We describe the coupling of holomorphic Chern-Simons theory at large N with Kodaira- Spencer gravity. We explain a new anomaly cancellation mechanism at all loops in perturbation theory for open-closed topological B-model. At one loop this anomaly cancellation is analogous to the Green-Schwarz mechanism. As an application, we introduce a type I version of Kodaira-Spencer theory in complex dimension 5 and show that it can only be coupled to holomorphic Chern-Simons theory with gauge group SO(32) at quantum level. This coupled system is conjectured to be a supersymmetric localization of type I string theory.
