We introduce the notion of bicolored diagrams which are closely related to the region crossing changes. Moreover, we refine Cheng’s results on the region crossing changes and propose a certain way to calculate the Arf invariant of a proper link using a bicolored diagram.

区域交叉变化、双色图和 Arf 不变量

我们引入了与区域交叉变化密切相关的双色图的概念。此外,我们改进了Cheng关于区域交叉变化的结果,并提出了一种使用双色图计算适当链路的Arf不变量的方法。
