本文描述了一个多项式不变量的虚拟节点,定义在一个整数标记的虚拟节点图。这个标签被认为是来自一个基本上独特的结构,仿射平面biquandle平面虚拟图。不变量详细讨论了许多例子,包括它与以前的这种类型的不变量,我们展示了如何从相同的数据构建瓦西里耶夫不变量。
This paper describes a polynomial invariant of virtual knots that is defined in terms of an integer labeling of the virtual knot diagram. This labeling is seen to derive from an essentially unique structure of affine flat biquandle for flat virtual diagrams. The invariant is discussed in detail with many examples,including its relation to previous invariants of this type and we show how to construct Vassiliev invariants from the same data.
