Jasper van de Kreeke

AI总结:

本文以带穿孔曲面的温和代数为基础,利用形变 Kadeishvili 定理构造并验证相对 Fukaya 范畴模型 Gtl_q Q,为形变镜像对称提供关键技术环节。

摘要:

相对 Fukaya 范畴很难构造。在本文中,我们在带穿孔曲面的情形下给出了一种非常显式的构造。出发点是与带穿孔曲面 Q 相关联的温和代数 Gtl Q。我们用于相对 Fukaya 范畴的模型是形变 Gtl_q Q,它在每个穿孔处具有一个形式形变参数。通过计算导出范畴 H Tw Gtl_q Q 上 A_∞-结构的很大一部分,我们验证了 Gtl_q Q 是相对 Fukaya 范畴的一个模型。核心方法是 arXiv:2308.08026 中给出的形变 Kadeishvili 定理。本文的技术贡献包括:(1)一种从带状对象中消除曲率的构造;(2)一种分析 Kadeishvili 树的方法;(3)形变 Kadeishvili 树与相对 Fukaya 圆盘之间的匹配。本文是由三篇论文组成的系列中的第二篇,该系列旨在对带穿孔曲面的镜像对称进行形变。

英文摘要:

Relative Fukaya categories are hard to construct. In this paper, we provide a very explicit construction in the case of punctured surfaces. The starting point is the gentle algebra $ \operatorname{Gtl} Q $ associated with a punctured surface $ Q $. Our model for the relative Fukaya category is a deformation $ \operatorname{Gtl}_q Q $ which has one formal deformation parameter per puncture. We verify that $ \operatorname{Gtl}_q Q $ is a model for the relative Fukaya category by computing a large part of the $ A_\infty $-structure on the derived category $ \operatorname{H}\operatorname{Tw}\operatorname{Gtl}_q Q $. The core method is the deformed Kadeishvili theorem from arXiv:2308.08026. The paper's technical contributions include (1) a construction for removing curvature from band objects, (2) a method for analyzing Kadeishvili trees, (3) a matching between deformed Kadeishvili trees and relative Fukaya disks. This paper is the second in a series of three, whose aim it is to deform mirror symmetry for punctured surfaces.
