法里斯在2011年的博士论文中证明了黎曼曲面上的预量子化丛的ECH同构为Z/2 Z-分次群到其基的同调的外代数。我们通过计算链复合体上的Z-分级来扩展这一结果,从而更好地理解这种同构。我们填充了一些技术细节,包括Morse-Bott直接极限参数和一些扭曲的界限。前者要求过滤Seiberg-Witten Floer上同调和Hutchings-Taubes建立的过滤ECH之间的同构。后者需要Cristofaro-Gardiner-Hutchings-Zhang关于伪全纯曲线的高阶渐近性的工作。在随后的论文中,我们计划将这些方法扩展到塞弗特纤维空间,并将ECH U-映射与基的轨道Gromov-Witten不变量联系起来。
The 2011 PhD thesis of Farris demonstrated that the ECH of a prequantization bundle over a Riemann surface is isomorphic as a Z/2Z-graded group to the exterior algebra of the homology of its base. We extend this result by computing the Z-grading on the chain complex, permitting a finer understanding of this isomorphism. We fill in some technical details, including the Morse-Bott direct limit argument and some writhe bounds. The former requires the isomorphism between filtered Seiberg-Witten Floer cohomology and filtered ECH as established by Hutchings--Taubes. The latter requires the work on higher asymptotics of pseudoholomorphic curves by Cristofaro-Gardiner--Hutchings--Zhang. In a subsequent paper, we plan to extend these methods for Seifert fiber spaces and relate the ECH U-map to orbifold Gromov-Witten invariants of the base.
