关于闭三辫的一个注记

A note on closed 3-braids

Joan S. Birman, William W. Menasco

摘要:

结和链接是封闭的3-辫子是一个非常特殊的类。像2桥结和链接,他们是足够简单,承认一个完整的分类。与此同时,它们也足够丰富,可以作为例子的来源,幸运的话,研究人员可以在这些例子上测试各种假设。这篇评论文章的目的是收集在一起,在一个地方,一些工具,特别是结和链接的编织指数3,在一种形式,可能是有用的那些谁需要计算,并需要确切地知道所有的例外情况。我们还利用它作为一个机会,审查什么是已知的,并提出一些开放的问题。

英文摘要:

Knots and links which are closed 3-braids are a very special class. Like 2-bridge knots and links, they are simple enough to admit a complete classification. At the same time they are rich enough to serve as a source of examples on which, with luck, a researcher may be able to test various conjectures. The goal of this review article is to gather together, in one place, some of the tools that are special to knots and links of braid index 3, in a form that could be useful for those who have a need to calculate, and need to know precisely all the exceptional cases. We also use it as an opportunity to review what is known and suggest some open questions.
