关于虚纽结的虚交叉数

On Virtual Crossing Numbers for Virtual Knots

Vassily Olegovich Manturov

摘要:

本文的目的是证明一些家庭的虚拟节点的虚拟交叉的最小数量的增长二次关于经典交叉的最小数量。所有以前已知的估计虚拟交叉数主要是不超过线性的经典交叉的数量(或,什么是相同的,在虚拟节点图的边缘数),并没有发现虚拟结与虚拟交叉数大于的经典交叉数。

英文摘要:

The aim of the present paper is to prove that the minimal number of virtual crossings for some families of virtual knots grows quadratically with respect to the minimal number of classical crossings. All previously known estimates for virtual crossing number were principally no more than linear in the number of classical crossings (or, what is the same, in the number of edges of a virtual knot diagram) and no virtual knot was found with virtual crossing number greater than the classical crossing number.
