曲面上的哈密顿 Floer 理论

Hamiltonian Floer theory on surfaces

Dustin Connery-Grigg

AI总结:

本文利用有限能量叶状结构思想,发展了曲面上哈密顿同痕动力学与链级 Floer 理论的联系,提出生成正向横截叶状结构的 Floer 理论方法,并基于 Floer 链的拓扑刻画定义了新型谱不变量。

摘要:

我们利用源自 Hofer-Wysocki-Zehnder 有限能量叶状结构理论的思想,发展了曲面 $Σ$ 上哈密顿同痕的定性动力学与其链级 Floer 理论之间的联系。对于每一个“相对于 Morse 范围极大不相连”的加帽 $1$-周期轨道集合,我们在 $S^1 \times Σ$ 上关联了一个奇异叶状结构,该结构正向横截于向量场 $\partial_t \oplus X^H$,并且由相关的 Floer 模空间以直接的方式组装而成。这提供了一种 Floer 理论方法,用于生成 Le Calvez 曲面同胚正向横截叶状结构理论中出现的那种叶状结构。此外,我们对既在 $CF_*(H,J)$ 中表示基本类、又位于某个链级 PSS 映射像中的 Floer 链给出了纯拓扑刻画。这导出了一族新的谱不变量,它们具有许多与 Oh-Schwarz 谱不变量相同的形式性质,并且我们完全用动力学语言计算了与基本类相关联的新谱不变量。这显著扩展了 Humilière-Le Roux-Seyfaddini 在 arXiv:1502.03834 中发起的项目。

英文摘要:

We develop connections between the qualitative dynamics of Hamiltonian isotopies on a surface $Σ$ and their chain-level Floer theory using ideas drawn from Hofer-Wysocki-Zehnder's theory of finite energy foliations. We associate to every collection of capped $1$-periodic orbits which is `maximally unlinked relative the Morse range' a singular foliation on $S^1 \times Σ$ which is positively transverse to the vector field $\partial_t \oplus X^H$ and which is assembled in a straight-forward way from the relevant Floer moduli spaces. This provides a Floer-theoretic method for producing foliations of the type which appear in Le Calvez's theory of positively transverse foliations for surface homeomorphisms. Additionally, we provide a purely topological characterization of those Floer chains which both represent the fundamental class in $CF_*(H,J)$, and which lie in the image of some chain-level PSS map. This leads to the definition of a novel family of spectral invariants which share many of the same formal properties as the Oh-Schwarz spectral invariants, and we compute the novel spectral invariant associated to the fundamental class in entirely dynamical terms. This significantly extends a project initiated by Humilière-Le Roux-Seyfaddini in arXiv:1502.03834.
