虚拟涂鸦的Alexander和Markov定理

Alexander and Markov theorems for virtual doodles

Neha Nanda, Mahender Singh

摘要:

对封闭定向曲面上没有三重或更高相交的浸入圆的有限集合的某些合痕类的研究可以被认为是虚纽结理论的平面模拟,其中亏格为零的情况对应于经典的纽结理论。亚历山大和马尔可夫定理亏格为零的情况下是已知的,其中发挥作用的群体是孪生群体,一类直角考克斯特群只有远交换关系。本文的目的是证明亚历山大和马尔可夫定理的高亏格的情况下,群的作用是由一类新的群称为虚拟孪生群,在一个自然的方式扩展孪生群。

英文摘要:

Study of certain isotopy classes of a finite collection of immersed circles without triple or higher intersections on closed oriented surfaces can be thought of as a planar analogue of virtual knot theory where the genus zero case corresponds to classical knot theory. Alexander and Markov theorems for the genus zero case are known where the role of groups is played by twin groups, a class of right angled Coxeter groups with only far commutativity relations. The purpose of this paper is to prove Alexander and Markov theorems for higher genus case where the role of groups is played by a new class of groups called virtual twin groups which extends twin groups in a natural way.
