Heegaard弗洛尔同调研究综述

A survey of Heegaard Floer homology

Andras Juhasz

摘要:

这项工作有两个目标。第一个是提供一个概念性的介绍Heegaard弗洛尔同调,第二个是调查目前的状态,该领域,而不是旨在完整性。在回顾了Heegaard弗洛尔同调的结构之后,我们列出了它的一些最重要的应用。其中许多是纯粹的拓扑结果,而不是指Heegaard弗洛尔同调本身。然后,我们简要概述了拉格朗日交弗洛尔同调的构造。我们构造了Heegaard Floer链复形作为上述的一个特例,并试图激发各种看似特别的特征,如可容许性,基点的选择和Spin^c-结构的作用。我们还讨论了不变性的证明下的同调同构的所有选择,以及如何定义Heegaard弗洛尔同调使用这在函子的方式(自然)。接下来,我们将解释为什么Heegaard弗洛尔同调是可计算的,以及它如何适用于各种组合描述。最后一章给出了缝合弗洛尔同调的定义和应用的概述,其中包括一些关键证明的草图。在整个过程中,我们一直试图收集该地区的一些重要的开放式文物。例如,对其中两个问题的肯定回答将给出庞加莱猜测的新证明。

英文摘要:

This work has two goals. The first is to provide a conceptual introduction to Heegaard Floer homology, the second is to survey the current state of the field, without aiming for completeness. After reviewing the structure of Heegaard Floer homology, we list some of its most important applications. Many of these are purely topological results, not referring to Heegaard Floer homology itself. Then, we briefly outline the construction of Lagrangian intersection Floer homology. We construct the Heegaard Floer chain complex as a special case of the above, and try to motivate the role of the various seemingly ad hoc features such as admissibility, the choice of basepoint, and Spin^c-structures. We also discuss the proof of invariance of the homology up to isomorphism under all the choices made, and how to define Heegaard Floer homology using this in a functorial way (naturality). Next, we explain why Heegaard Floer homology is computable, and how it lends itself to the various combinatorial descriptions. The last chapter gives an overview of the definition and applications of sutured Floer homology, which includes sketches of some of the key proofs. Throughout, we have tried to collect some of the important open conjectures in the area. For example, a positive answer to two of these would give a new proof of the Poincaré conjecture.
