Knotoids的奇偶性

Parity in Knotoids

Neslihan Gügümcü, Louis Kauffman

摘要:

本文研究了$S^2$和$\mathbb{R}^2$中与虚结有关的拟结中的宇称概念。我们表明,虚拟封闭映射是不满射,并给出具体的例子,虚拟结不在图像中。我们介绍了一个平面版本的奇偶括号多项式的knotoid在$\mathbb{R}^2$。利用Nikonov/Manturov定理证明了Turaev的一个猜想,证明了纽结型knotoid的极小图的高度为零.

英文摘要:

This paper investigates the parity concept in knotoids in $S^2$ and in $\mathbb{R}^2$ in relation with virtual knots. We show that the virtual closure map is not surjective and give specific examples of virtual knots that are not in the image. We introduce a planar version of the parity bracket polynomial for knotoids in $\mathbb{R}^2$. By using the Nikonov/Manturov theorem on minimal diagrams of virtual knots we prove a conjecture of Turaev showing that minimal diagrams of knot-type knotoids have zero height.
