高亏格曲线的同调镜像对称

Homological mirror symmetry for curves of higher genus

Alexander I. Efimov

AI总结:

本文将 Seidel 关于亏格二曲线的同调镜像对称结果推广到亏格 g≥3 曲线,并证明超曲面奇点的形式类型可由其 Landau-Ginzburg 膜范畴重构。

摘要:

Katzarkov 提出了 Kontsevich 镜像对称猜想的一个推广,涵盖某些一般型簇。Seidel \cite{Se} 在亏格二曲线这一最简单情形证明了该猜想的一个版本。基于 Seidel 的论文,我们证明了亏格 $g\geq 3$ 曲线的该猜想(同一版本),将亏格 $g$ 曲线的 Fukaya 范畴与某个奇异曲面上的 Landau-Ginzburg 膜范畴联系起来。我们还证明了超曲面奇点的一种重构定理。即,在某些技术假设下,超曲面奇点的形式类型(即一个形式幂级数在形式变量替换下的等价类)可以从其 D$(\Z/2)$-分次 Landau-Ginzburg 膜范畴中重构出来。精确陈述见定理 1.2。

英文摘要:

Katzarkov has proposed a generalization of Kontsevich's mirror symmetry conjecture, covering some varieties of general type. Seidel \cite{Se} has proved a version of this conjecture in the simplest case of the genus two curve. Basing on the paper of Seidel, we prove the conjecture (in the same version) for curves of genus $g\geq 3,$ relating the Fukaya category of a genus $g$ curve to the category of Landau-Ginzburg branes on a certain singular surface. We also prove a kind of reconstruction theorem for hypersurface singularities. Namely, formal type of hypersurface singularity (i.e. a formal power series up to a formal change of variables) can be reconstructed, with some technical assumptions, from its D$(\Z/2)$-G category of Landau-Ginzburg branes. The precise statement is Theorem 1.2.
