$L^2$ -Burau映射和$L^2$ -Alexander挠

$L^2$-Burau maps and $L^2$-Alexander torsions

Fathi Ben Aribi, Anthony Conway

摘要:

众所周知,辫群的Burau表示可以用来恢复辫的闭包的Alexander多项式。定义了$L^2$ -Burau映射,并利用它计算了链环的$L^2$ -Alexander挠率.作为一个应用,我们证明了$L^2$ -Burau映射区分更多的辫子比Burau表示。

英文摘要:

It is well known that the Burau representation of the braid group can be used to recover the Alexander polynomial of the closure of a braid. We define $L^2$-Burau maps and use them to compute some $L^2$-Alexander torsions of links. As an application, we prove that the $L^2$-Burau maps distinguish more braids than the Burau representation.
