琼斯多项式的无符号状态模型

Unsigned state models for the Jones polynomial

Iain Moffatt

摘要:

Jones多项式可以表示为符号平面图的Potts和点分拆函数,这是一个众所周知的基本结果。在这里,我们考虑的琼斯多项式的状态模型的无符号图的建设,并表明,琼斯多项式的任何链接可以表示为一个顶点模型的无符号嵌入图。在推导这一结果的过程中,我们证明了对于3-球面中的每个链接图,存在一个具有相同Kauffman括号的加厚曲面中的交替链接图(和交替虚拟链接)。我们还恢复了两个最近的结果在文献中有关的琼斯和Bollobas-Riordan多项式,并表明它们产生于两个不同的解释相同的嵌入图。

英文摘要:

It is well a known and fundamental result that the Jones polynomial can be expressed as Potts and vertex partition functions of signed plane graphs. Here we consider constructions of the Jones polynomial as state models of unsigned graphs and show that the Jones polynomial of any link can be expressed as a vertex model of an unsigned embedded graph. In the process of deriving this result, we show that for every diagram of a link in the 3-sphere there exists a diagram of an alternating link in a thickened surface (and an alternating virtual link) with the same Kauffman bracket. We also recover two recent results in the literature relating the Jones and Bollobas-Riordan polynomials and show they arise from two different interpretations of the same embedded graph.
