复曲面Blowup中非阿基米德柱面数的计算

Computing Non-Archimedean Cylinder Counts in Blowups of Toric Surfaces

Thorgal Hinault

摘要:

全纯圆盘的计数是SYZ镜像对称方法的核心。在非阿基米德框架中,这些计数被表示为解析圆柱的计数。在简单的情况下,如集群品种,这些计数可以从由散射图编码的组合算法中提取。相关的散射图编码有关无穷小解析圆柱体的信息。本文利用非阿基米德Gromov-Witten理论和热带数据参数化的退化过程,给出了仿射对数Calabi-Yau曲面上一类限制圆柱的计数与复曲面上一次爆破的计数之间的关系式.这个封闭形式的公式与散射图方法相结合。

英文摘要:

Counts of holomorphic disks are at the heart of the SYZ approach to mirror symmetry. In the non archimedean framework, these counts are expressed as counts of analytic cylinders. In simple cases, such as cluster varieties, these counts can be extracted from a combinatorial algorithm encoded by a scattering diagram. The relevant scattering diagram encodes information about infinitesimal analytic cylinders. In this paper, we give a formula relating counts of a restricted class of cylinders on affine log Calabi Yau surfaces to counts on a single blowup of a toric surface, using non archimedean Gromov Witten theory and a degeneration procedure parametrized by tropical data. This closed form formula constrasts with the scattering diagram approach.
