非紧流形上Morse同调的不变性

Invariance property of Morse homology on noncompact manifolds

Jungsoo Kang

摘要:

本文主要研究非紧流形上Morse同调的不变性。我们期望将本文的结果应用到几种类型的弗洛尔同调中,从而纯粹从公理和代数上定义Morse同调。非紧流形上的Morse同调通常取决于Morse函数的选择;很容易看出临界点可以沿着非紧流形上Morse函数的同伦逃逸。更糟糕的是,即使临界点是活的,同调类也可以沿着同伦逃逸。这篇文章的目的是双重的。首先,我们给出了一个例子,打破了不变性的同伦类的逃逸,并找到适当的增长条件同伦,防止这种逃逸。这利用了分叉方法。另一个目标是将第一个结果应用于Rabinowitz弗洛尔同调的不变性问题。Rabinowitz弗洛尔同调的分支方法还没有研究出来。在此基础上,研究了Rabinowitz弗洛尔同调的不变性问题,证明了分支方法对Rabinowitz弗洛尔同调是适用的.

英文摘要:

In this article, we focus on the invariance property of Morse homology on noncompact manifolds. We expect to apply outcomes of this article to several types of Floer homology, thus we define Morse homology purely axiomatically and algebraically. The Morse homology on noncompact manifolds generally depends on the choice of Morse functions; it is easy to see that critical points may escape along homotopies of Morse functions on noncompact manifolds. Even worse, homology classes also can escape along homotopies even though critical points are alive. The aim of the article is two fold. First, we give an example which breaks the invariance property by the escape of homology classes and find appropriate growth conditions on homotopies which prevent such an escape. This takes advantage of the bifurcation method. Another goal is to apply the first results to the invariance problem of Rabinowitz Floer homology. The bifurcation method for Rabinowitz Floer homology, however, is not worked out yet. Thus believing that the bifurcation method is applicable to Rabinowitz Floer homology, we study the invariance problems of Rabinowitz Floer homology.
