拓扑弦论中的新反常现象

New Anomalies in Topological String Theory

Paul L. H. Cook, Hirosi Ooguri, Jie Yang

摘要:

我们证明了紧致卡-丘流形上D-膜的拓扑弦配分函数具有新的反常,这些反常破坏了全纯反常方程的递归结构,并引入了对错误模的依赖(如A-模型中的复结构模),除非圆盘单点函数为零.这为Walcher最近在arXiv:0712.2775中使用拓扑弦配分函数计算M理论中BPS态的结果提供了一个微观解释。消失盘单点函数的相关性,以大$N$对偶紧凑的卡-丘流形。

英文摘要:

We show that the topological string partition function with D-branes on a compact Calabi-Yau manifold has new anomalies that spoil the recursive structure of the holomorphic anomaly equation and introduce dependence on wrong moduli (such as complex structure moduli in the A-model), unless the disk one-point functions vanish. This provides a microscopic explanation for the recent result of Walcher in arXiv:0712.2775 on counting of BPS states in M-theory using the topological string partition function. The relevance of vanishing disk one-point functions to large $N$ duality for compact Calabi-Yau manifolds is noted.
