一个作为纽结不变量的独立系统

An independence system as knot invariant

Usman Ali, Iffat Fida Hussain

摘要:

在这篇文章中,我们定义了一个经典的纽结图的独立系统,并证明了独立系统是一个纽结不变量交替纽结。本文还讨论了极小可解集的交换性质。最后,我们表明,有结图的独立系统是一个拟阵,并有结图,它不是。

英文摘要:

In this article, we define an independence system for a classical knot diagram and prove that the independence system is a knot invariant for alternating knots. We also discuss the exchange property for minimal unknotting sets. Finally, we show that there are knot diagrams where the independence system is a matroid and there are knot diagrams where it is not.
