缠绕Floer上同调与拉格朗日对应

Wrapped Floer cohomology and Lagrangian correspondences

Yuan Gao

摘要:

我们研究了Liouville流形之间的拉格朗日对应关系,并构造了包裹类之间的函子。研究自然提出了比较乘积流形的两个版本的包裹类范畴的问题,我们证明了在包裹Floer上同调水平上的拟同构。为了证明这些函子从拉格朗日对应构造的可表示性,我们介绍了包装下的拉格朗日对应的几何组成,作为新的类的对象在包装类,我们证明代表函子通过建立一个规范的同构绗缝版本的包装Floer上同调几何组成。

英文摘要:

We study Lagrangian correspondences between Liouville manifolds and construct functors between wrapped Fukaya categories. The study naturally brings up the question on comparing two versions of wrapped Fukaya categories of the product manifold, which we prove quasi-isomorphism on the level of wrapped Floer cohomology. To prove representability of these functors constructed from Lagrangian correspondences, we introduce the geometric compositions of Lagrangian correspondences under wrapping, as new classes of objects in the wrapped Fukaya category, which we prove to represent the functors by establishing a canonical isomorphism of quilted version of wrapped Floer cohomology under geometric composition.
