基于辛变换的五次三重的Landau-Ginzburg/Calabi-Yau对应

Landau-Ginzburg/Calabi-Yau correspondence for quintic three-folds via symplectic transformations

Alessandro Chiodo, Yongbin Ruan

摘要:

我们计算了最近引进的Fan-Jarvis-Ruan-Witten五次多项式亏格为零的W-曲线理论,并通过辛变换证明了它与Gromov-Witten五次三重亏格为零的理论相匹配。更具体地说,我们证明了J-函数编码的Fan-Jarvis-Ruan-Witten理论的A侧通过镜像映射的I-函数体现的周期积分在Gepner点的B侧。这种识别在曲线模的枚举几何中记录了物理上的朗道-金兹伯格/卡拉比-丘对应,匹配物理学家黄、克莱姆和夸肯布什在盖普纳点计算的亏格零不变量,并通过吉文塔尔的量子化预测了五次三重的完整高阶亏格势与范-贾维斯-阮-威滕理论之间的关系。

英文摘要:

We compute the recently introduced Fan-Jarvis-Ruan-Witten theory of W-curves in genus zero for quintic polynomials in five variables and we show that it matches the Gromov-Witten genus-zero theory of the quintic three-fold via a symplectic transformation. More specifically, we show that the J-function encoding the Fan-Jarvis-Ruan-Witten theory on the A-side equals via a mirror map the I-function embodying the period integrals at the Gepner point on the B-side. This identification inscribes the physical Landau-Ginzburg/Calabi-Yau correspondence within the enumerative geometry of moduli of curves, matches the genus-zero invariants computed by the physicists Huang, Klemm, and Quackenbush at the Gepner point, and yields via Givental's quantization a prediction on the relation between the full higher genus potential of the quintic three-fold and that of Fan-Jarvis-Ruan-Witten theory.
