关于透镜空间中的纽结和链环

On knots and links in lens spaces

Alessia Cattabriga, Enrico Manfredi, Michele Mulazzani

摘要:

本文研究了透镜空间中纽结和链环的一些性质。也就是说,如果我们把透镜空间看作是单位球$B^{3}$的商,并适当地确定边界点,那么我们就可以把链环投影到$B^{3}$的赤道盘上,得到它们的正则图。在这场比赛中,我们获得了一个完整的有限集Reidemeister型移动建立等价,环境合痕,Wirtinger型介绍的基本群的补充的链接和一个图形的方法,使第一个同调群。我们还计算了这类链环的Alexander多项式和扭曲的Alexander多项式,显示了它们与Reidemeister扭曲的相关性。

英文摘要:

In this paper we study some aspects of knots and links in lens spaces. Namely, if we consider lens spaces as quotient of the unit ball $B^{3}$ with suitable identification of boundary points, then we can project the links on the equatorial disk of $B^{3}$, obtaining a regular diagram for them. In this contest, we obtain a complete finite set of Reidemeister type moves establishing equivalence, up to ambient isotopy, a Wirtinger type presentation for the fundamental group of the complement of the link and a diagrammatic method giving the first homology group. We also compute Alexander polynomial and twisted Alexander polynomials of this class of links, showing their correlation with Reidemeister torsion.
