内容简介

As the the title suggests, the goal of this book is to give the reader a taste of the “unreasonable effectiveness” of Morse theory. The main idea behind thistechnique can be easily visualized.
Suppose M is a smooth, compact manifold, which for simplicity we as-sume is embedded in a Euclidean space E. We would like to understand basictopological invariants of M such as its homology, and we attempt a “slicing” technique.

前言/序言

  As the the title suggests, the goal of this book is to give the reader a taste of the “unreasonable effectiveness” of Morse theory. The main idea behind thistechnique can be easily visualized.
  Suppose M is a smooth, compact manifold, which for simplicity we as-sume is embedded in a Euclidean space E. We would like to understand basictopological invariants of M such as its homology, and we attempt a “slicing” technique.
  We fix a unit vector u in E and we start slicing M with the family of hyperplanes perpendicular to u. Such a hyperplane will in general intersectM along a submanifold (slice). The manifold can be recovered by continuouslystacking the slices on top of each other in the same order as they were cut out of M.
  Think of the collection of slices as a deck of cards of various shapes. If welet these slices continuously pile up in the order they were produced, we noticean increasing stack of slices. As this stack grows, we observe that there aremoments of time when its shape suffers a qualitative change. Morse theoryis about extracting quantifiable information by studying the evolution of theshape of this growing stack of slices.

在适当的小范围内联结任意两点的测地线是最短线,所以测地线又称为短程线。

1.1 相关定理及推论

评分

微分拓扑学的一个重要分支。通常指两部分内容:一是微分流形上可微函数的莫尔斯理论,即临界点理论;二是变分问题的莫尔斯理论,即大范围变分法。

评分

数学类基础用书,值得参考

的分支。它是H.M.莫尔斯在20世纪30年代创立的。由莫尔斯理论得知 ,微分流形与其上的光滑函数紧密相关,利用光滑函数不仅能研究微分流形的局部性质,而且某些光滑函数例如莫尔斯函数包含了刻划流形整体性质的丰富信息。莫尔斯理论主要分两部分,一是临界点理论,一是它在大范围变分问题上的应用。一个莫尔斯函数也是一个非简谐振子的一种表达法。

质量不错,以后还会购买。
