一个微妙的新不变量的框架结和链接

A subtle new invariant for framed knots and links

Sostenes Lins

摘要:

我们生产的一个结或一个链接,承认一个不变的专业化下波利亚克最近的一套生成的4 Reidemeister移动平面图上的面部状态和。从而得到了框架连杆的一个同痕不变量。每个状态都是图的面完全着色成白色和黑色的面,这样就不会有两个黑色的面共享一条边。每个状态在16个变量的环中导出一个单项式。状态的总和,适当地专门定义了新的不变量。尽管它的简单性,它补充琼斯不变量在区分镜像对的链接。特别地,它证明了$9_{42}$不同于它的镜像。对于这对节点,琼斯多项式和考夫曼二元多项式都失败了。

英文摘要:

We produce a facial state sum on plane diagrams of a knot or a link which admits an invariant specialization under Polyak's recent set of generating of 4 Reidemeister moves. Thus an isotopy invariant of framed links is obtained. Each state is a complete coloring of the faces of the diagram into white and black faces so that no two black faces share an edge. Each state induces a monomial in a ring of 16 variables. The sum of the states, properly specialized defines the new invariant. In despite of its simplicity it complements Jones invariant in distinguishing mirror pairs of links. In particular it proves that $9_{42}$ is distinct from its mirror image. For this pair of knots both the Jones Polynomial and Kauffman 2-variable polynomial fail.
