交错虚链路的Jones多项式的跨度

Span of the Jones polynomial of an alternating virtual link

Naoko Kamada

摘要:

对于定向虚拟链路,L.H.考夫曼定义了f多项式(琼斯多项式)。虚拟链接图的支撑亏格是该图可嵌入的曲面的最小曲面的亏格。本文证明了交错虚环L的f-多项式的跨距由L的任意交错图的交叉数和图的支撑亏格决定。它是Kauffman-Murasugi-Thistlethwaite定理的推广。我们还证明了一个类似的结果,从一个交替的虚拟链路图虚拟一个真正的交叉得到的虚拟链路图。因此,这样的图不等同于经典的链接图。

英文摘要:

For an oriented virtual link, L.H. Kauffman defined the f-polynomial (Jones polynomial). The supporting genus of a virtual link diagram is the minimal genus of a surface in which the diagram can be embedded. In this paper we show that the span of the f-polynomial of an alternating virtual link L is determined by the number of crossings of any alternating diagram of L and the supporting genus of the diagram. It is a generalization of Kauffman-Murasugi-Thistlethwaite's theorem. We also prove a similar result for a virtual link diagram that is obtained from an alternating virtual link diagram by virtualizing one real crossing. As a consequence, such a diagram is not equivalent to a classical link diagram.
