关于射影空间中Fano超曲面的类范畴

On the Fukaya category of a Fano hypersurface in projective space

Nick Sheridan

摘要:

本文研究Fano超曲面$X \subset \mathbb{CP}^n$的范畴.因为这些辛流形是单调的,所以在定义辛流形范畴时所涉及的分析和代数都大大简化了。本文的第一部分致力于建立单调情形下的Chronaya范畴的主要结构:闭开弦映射,弱真Calabi-Yau结构,Abouzaid分裂生成准则,以及当包含弱有界上链时它们的类似物。然后,我们转向计算的超曲面$X$的Pakaya类别:我们构造一个配置的单调拉格朗日球在$X$,并计算相关的磁盘潜力。结果与$X$镜像的Hori-Vafa超势一致(直到Fano指数$1$情况下的恒定移位)。作为结果,我们给出了关于$X$的Kontsevich同调镜像对称猜想的一个证明.我们还解释了如何提取非平凡信息的Gromov-Witten不变量的$X$从它的类。

英文摘要:

This paper is about the Fukaya category of a Fano hypersurface $X \subset \mathbb{CP}^n$. Because these symplectic manifolds are monotone, both the analysis and the algebra involved in the definition of the Fukaya category simplify considerably. The first part of the paper is devoted to establishing the main structures of the Fukaya category in the monotone case: the closed-open string maps, weak proper Calabi-Yau structure, Abouzaid's split-generation criterion, and their analogues when weak bounding cochains are included. We then turn to computations of the Fukaya category of the hypersurface $X$: we construct a configuration of monotone Lagrangian spheres in $X$, and compute the associated disc potential. The result coincides with the Hori-Vafa superpotential for the mirror of $X$ (up to a constant shift in the Fano index $1$ case). As a consequence, we give a proof of Kontsevich's homological mirror symmetry conjecture for $X$. We also explain how to extract non-trivial information about Gromov-Witten invariants of $X$ from its Fukaya category.
