摘要

给定一个结,我们开发了寻找辫子代表的方法,使简单行走的数量最小化。这样的辫子导致了一种计算K的有色琼斯多项式的有效方法,它遵循了由阿蒙德开发并由哈吉和莱维特实现的方法。我们用这种方法计算了结点$5_2,$ 6_1,$和$7_2$的封闭形式的有色琼斯多项式。简单行走集在辫状体的反射、旋转和循环置换下可以发生变化,并证明了辫状体的简单行走集与其循环置换下的反射行走集之间的不变性。我们研究了环面结族简单行走次数的增长率。最后,我们提出了一个编织词表,使结的简单行走次数减少到13个交叉点。

Braid representatives minimizing the number of simple walks
Given a knot, we develop methods for finding the braid representative that minimizes the number of simple walks. Such braids lead to an efficient method for computing the colored Jones polynomial of $K$, following an approach developed by Armond and implemented by Hajij and Levitt. We use this method to compute the colored Jones polynomial in closed form for the knots $5_2, 6_1,$ and $7_2$. The set of simple walks can change under reflection, rotation, and cyclic permutation of the braid, and we prove an invariance property which relates the simple walks of a braid to those of its reflection under cyclic permutation. We study the growth rate of the number of simple walks for families of torus knots. Finally, we present a table of braid words that minimize the number of simple walks for knots up to 13 crossings.
