演化方法与有色纽结多项式的“微分族”

Evolution method and "differential hierarchy" of colored knot polynomials

A. Mironov, A. Morozov, An. Morozov

摘要:

我们认为编织物内的任意结,提供了一个多参数的家庭结的重复模式,这取决于“进化”参数,它控制的重复次数。结(超)多项式对这样的演化参数的依赖性是很容易找到的。我们应用这种演化方法来研究的家庭的结和链接,其中包括的情况下,只有两个平行和反平行股的编织,像普通的扭曲和2股环面结/链接和反向2股链接。当答案之前可用时,它们立即被复制,并且添加了一个基本上新的“双编织物”的例子,这是平行和反平行2股编织物的组合。这项研究有助于我们完全清晰地揭示并部分研究有色HOMFLY多项式的神秘层次结构,至少在(反)对称表示中,它将8字形结的原始观察扩展到许多(大概是所有)结。我们证明,这种结构是典型的尊重的t-变形的超多项式。

英文摘要:

We consider braids with repeating patterns inside arbitrary knots which provides a multi-parametric family of knots, depending on the "evolution" parameter, which controls the number of repetitions. The dependence of knot (super)polynomials on such evolution parameters is very easy to find. We apply this evolution method to study of the families of knots and links which include the cases with just two parallel and anti-parallel strands in the braid, like the ordinary twist and 2-strand torus knots/links and counter-oriented 2-strand links. When the answers were available before, they are immediately reproduced, and an essentially new example is added of the "double braid", which is a combination of parallel and anti-parallel 2-strand braids. This study helps us to reveal with the full clarity and partly investigate a mysterious hierarchical structure of the colored HOMFLY polynomials, at least, in (anti)symmetric representations, which extends the original observation for the figure-eight knot to many (presumably all) knots. We demonstrate that this structure is typically respected by the t-deformation to the superpolynomials.
