“关于纽结Turaev属的考察”问题1的一个反例

A counterexample to Question 1 of "A survey on the Turaev genus of knots"

Cody Armond, Moshe Cohen

摘要:

在“关于Turaev属的结的调查”中,Champanerkar和Kofman提出了几个悬而未决的问题。第一个问题的多项式的系数计数的拟树的所有A带状图的数量从图的最小Turaev亏格是一个不变量的结。我们回答否定的显示从两个图$8_{21}$在KnotAtlas和KnotScape的反例。

英文摘要:

In "A survey on the Turaev genus of knots," Champanerkar and Kofman propose several open questions. The first asks whether the polynomial whose coefficients count the number of quasi-trees of the all-A ribbon graph obtained from a diagram with minimal Turaev genus is an invariant of the knot. We answer negatively by showing a counterexample obtained from the two diagrams of $8_{21}$ on the KnotAtlas and KnotScape.
