內容簡介

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.

讀者評價

評分

在大地綫上,各點的主麯率方嚮均與該點上麯麵法綫相閤。它在圓球麵上為大圓弧,在平麵上就是直綫。在大地測量中,通常用大地綫來代替法截綫,作為研究和計算橢球麵上各種問題。測地綫是在一個麯麵上,每一點處測地麯率均為零的麯綫。 麯麵上非直綫的麯綫是測地綫的充分必要條件是除瞭麯率為零的點以外,麯綫的主法綫重閤於麯麵的法綫。

評分

微分拓撲學的一個重要分支。通常指兩部分內容:一是微分流形上可微函數的莫爾斯理論,即臨界點理論;二是變分問題的莫爾斯理論,即大範圍變分法。

評分

2.2 局部最短性

評分

2 微分幾何的測地綫

評分

應該是比較適閤初學者的書,而且也不是很厚,值得一看。

評分

過麯麵上任一點,給定一個麯麵的切方嚮,則存在唯一一條測地綫切於此方嚮。

評分

應該是比較適閤初學者的書,而且也不是很厚,值得一看。
