log Calabi-Yau曲面上全纯圆柱的Enumeration。I

Enumeration of holomorphic cylinders in log Calabi-Yau surfaces. I

Tony Yue Yu

摘要:

我们定义了对数Calabi-Yau曲面上全纯圆柱的计数。虽然我们从一个复杂的日志卡-丘表面开始,计数是通过应用非阿基米德几何的方法来实现的。这就产生了新的几何不变量。此外,我们证明了计数满足对称性的性质。对del Pezzo曲面进行了详细的显式计算,验证了焦-焦奇异性的定解越壁公式。我们的全纯圆柱是为了给Gross,Hacking,Keel和Siebert的组合概念折线一个几何理解。我们的工具包括Berkovich空间,热带几何,Gromov-Witten理论和GAGA非阿基米德分析栈定理。

英文摘要:

We define the counting of holomorphic cylinders in log Calabi-Yau surfaces. Although we start with a complex log Calabi-Yau surface, the counting is achieved by applying methods from non-archimedean geometry. This gives rise to new geometric invariants. Moreover, we prove that the counting satisfies a property of symmetry. Explicit calculations are given for a del Pezzo surface in detail, which verify the conjectured wall-crossing formula for the focus-focus singularity. Our holomorphic cylinders are expected to give a geometric understanding of the combinatorial notion of broken line by Gross, Hacking, Keel and Siebert. Our tools include Berkovich spaces, tropical geometry, Gromov-Witten theory and the GAGA theorem for non-archimedean analytic stacks.
