环的Links-Gould不变量

The Links-Gould Invariant of Links

David De Wit, Louis H Kauffman, Jon R Links

摘要:

本文引入并详细研究了(1,1)缠结的一个不变量.这个不变量是从量子超代数U_q[gl(2)]的一族四维表示导出的|1)],将被称为Links-Gould不变量。我们发现,我们的不变量是不同的琼斯,HOMFLY和考夫曼多项式(检测手性的一些链接,这些不变量失败),它不区分突变体或逆。该方法的评价是基于一个抽象的张量状态模型的不变量,这是非常有用的计算以及理论探索。

英文摘要:

We introduce and study in detail an invariant of (1,1) tangles. This invariant, derived from a family of four dimensional representations of the quantum superalgebra U_q[gl(2|1)], will be referred to as the Links-Gould invariant. We find that our invariant is distinct from the Jones, HOMFLY and Kauffman polynomials (detecting chirality of some links where these invariants fail), and that it does not distinguish mutants or inverses. The method of evaluation is based on an abstract tensor state model for the invariant that is quite useful for computation as well as theoretical exploration.
