椭圆Calabi-Yau三重曲线的导出范畴计数

Curve counting on elliptic Calabi-Yau threefolds via derived categories

Georg Oberdieck, Junliang Shen

摘要:

本文证明了基上约化类上椭圆Calabi-Yau三重的Pandharipande-Thomas不变量的生成级数的Jacobi型的椭圆变换律。这证明了Huang、Katz和Klemm猜想的一部分。为了证明,我们构造了一个导出范畴的对合,并使用跨壁方法。我们表示的生成系列PT不变量的低亏格Gromov-Witten不变量和普遍的Jacobi形式。作为应用,我们证明了新的公式和恢复几个已知的公式PT不变量的$\mathrm{K3} \times E$,阿贝尔3倍,和STU模型。证明了$\mathrm{K3} \times E$关于$\mathrm{K3}$上的一个本原类的曲线计数不变量的生成序列是一个权为-10的拟Jacobi形式.这为Igusa尖点形式猜想提供了有力的证据。

英文摘要:

We prove the elliptic transformation law of Jacobi forms for the generating series of Pandharipande--Thomas invariants of an elliptic Calabi--Yau 3-fold over a reduced class in the base. This proves part of a conjecture by Huang, Katz, and Klemm. For the proof we construct an involution of the derived category and use wall-crossing methods. We express the generating series of PT invariants in terms of low genus Gromov--Witten invariants and universal Jacobi forms. As applications we prove new formulas and recover several known formulas for the PT invariants of $\mathrm{K3} \times E$, abelian 3-folds, and the STU-model. We prove that the generating series of curve counting invariants for $\mathrm{K3} \times E$ with respect to a primitive class on the $\mathrm{K3}$ is a quasi-Jacobi form of weight -10. This provides strong evidence for the Igusa cusp form conjecture.
