八个二重点以内的素纽结投影及其镜像列表

The tabulation of prime knot projections with their mirror images up to eight double points

Noboru Ito, Yusuke Takimura

摘要:

本文通过有限程序,系统地给出了至多八个二重点的素纽结投影及其镜像的完整表,没有冗余。本文利用J.H.的有理缠结的方法,通过列出至多四个二重点的缠结,给出至多八个二重点的纽结投影的列表。康威换句话说,对于一个给定的素结投影的交替结,我们展示了如何枚举可能的投影的交替结。同样,为了将纽结投影列表到环境合痕,我们引入了没有每个交叉的上/下信息的纽结投影的箭头图(定向高斯图),这些箭头图最初由M. Polyak和O.维罗结投影的每个箭头图完全检测结投影与其镜像之间的差异。

英文摘要:

This paper provides the complete table of prime knot projections with their mirror images, without redundancy, up to eight double points systematically thorough a finite procedure by flypes. In this paper, we show how to tabulate the knot projections up to eight double points by listing tangles with at most four double points by an approach with respect to rational tangles of J. H. Conway. In other words, for a given prime knot projection of an alternating knot, we show how to enumerate possible projections of the alternating knot. Also to tabulate knot projections up to ambient isotopy, we introduce arrow diagrams (oriented Gauss diagrams) of knot projections having no over/under information of each crossing, which were originally introduced as arrow diagrams of knot diagrams by M. Polyak and O. Viro. Each arrow diagram of a knot projection completely detects the difference between the knot projection and its mirror image.
