我们发展了一个顶点形式化的拓扑弦振幅的直纹表面上的任意数目的可约纤维嵌入在一个Calabi-Yau三倍。我们的构造是基于大N对偶性和关于退化环面作用的局部化。我们还讨论了使用相同的基本原则将我们的形式主义推广到更广泛的Calabi-Yau三倍。
We develop a vertex formalism for topological string amplitudes on ruled surfaces with an arbitrary number of reducible fibers embedded in a Calabi-Yau threefold. Our construction is based on large N duality and localization with respect to a degenerate torus action. We also discuss potential generalizations of our formalism to a broader class of Calabi-Yau threefolds using the same underlying principles.
