混合自旋P场的模堆栈(MSP)为计算五次Calabi-Yau(CY)三重群的所有亏格Gromov-Witten(GW)不变量提供了一个有效的算法。本文将该算法应用于亏格一的情形。我们使用局部化公式、文[,]中提出的算法和Zinger的包装技术来计算五次CY三折图的亏格一GW不变量。我们对公式的处理表明了每种类型的MSP图与每个物理阶段之间的对应关系:CY、Landau-Ginzburg或Conifold Point。在这个过程中,还发现了Givental的i-函数之间的新的微分关系。
The moduli stack of Mixed Spin P-fields (MSP) provides an effective algorithm to evaluate all genus Gromov–Witten (GW) invariants of the quintic Calabi–Yau (CY) three-folds. This paper is to apply the algorithm to the genus-one case. We use the localization formula, the proposed algorithm in [ , ], and Zinger’s packaging technique to compute the genus-one GW invariants of the quintic CY three-folds. Our approach to the formula suggests a correspondence between each type of MSP graphs with each physics’ phase: CY, Landau–Ginzburg, or conifold point. In this process, new differential relations among Givental’s I-functions are also discovered.
