本文证明了IIB型超弦的S-对偶如何导致最近证明的同一Calabi-Yau上的A-和B-模型拓扑弦的S-对偶：B-模型的D-瞬子对应于A-模型微扰振幅，A-模型的D-瞬子捕获微扰的B-模型振幅。此外，这证实了两个模型中新膜的存在。作为应用，我们解释了最近关于Calabi-Yau上A-模型拓扑弦的结果及其与熔化晶体统计力学模型的等价性。
In this paper we show how S-duality of type-IIB superstrings leads to an S-duality relating A- and B-model topological strings on the same Calabi-Yau as had been conjectured recently: D-instantons of the B-model correspond to A-model perturbative amplitudes and D-instantons of the A-model capture perturbative B-model amplitudes. Moreover this confirms the existence of new branes in the two models. As an application we explain the recent results concerning A-model topological strings on Calabi-Yau and its equivalence to the statistical mechanical model of melting crystal.
