复曲面弯矩纤维的规范Floer理论

Gauged Floer theory of toric moment fibers

Chris Woodward

摘要:

本文研究了Frauenfelder规范Lagrange Floer上同调的小区域极限。由此产生的上同调理论,我们称之为拟映射弗洛尔上同调,是一个障碍,拉格朗日在辛商的可拓性。我们使用的理论来重现的结果,aya-Oh-Ohta-Ono和Cho-Oh的不一定法诺复曲面品种的力矩纤维的非可伸缩性,并将其结果扩展到复曲面orbifolds,没有虚拟的基本链。最后我们描述了商中Floer上同调的一个几何关系。

英文摘要:

We investigate the small area limit of the gauged Lagrangian Floer cohomology of Frauenfelder. The resulting cohomology theory, which we call quasimap Floer cohomology, is an obstruction to displaceability of Lagrangians in the symplectic quotient. We use the theory to reproduce the results of Fukaya-Oh-Ohta-Ono and Cho-Oh on non-displaceability of moment fibers of not-necessarily-Fano toric varieties and extend their results to toric orbifolds, without virtual fundamental chains. Finally we describe a conjectural relationship to Floer cohomology in the quotient.
