A. Alexandrov, A. Mironov, A. Morozov, An. Morozov

摘要:

我们调查的TBEM特征值矩阵模型,它表示为相应的字符的平均值的环面结的非归一化的彩色HOMFLY多项式的推广的可能性。我们寻找一个相同类型的模型,这是一个常见的Chern-Simons混合高斯潜力,典型的厄米模型,和正弦范德蒙因子,典型的酉的。我们主要集中在家庭的扭曲结,其中包含一个单一的环面结,三叶草。事实证明,对于三叶草的TBEM措施提供了一个行动的拉普拉斯指数的琼斯多项式。这个过程可以应用于任意的节点,并提供了一个TBEM-like的N=2的情况下的积分表示。然而,在环面族之外,测度及其提升到更大的N都包含\hbar = \log q中的非平凡修正。一种可能性是吸收这些修正到拉普拉斯演化的变形更高的卡西米尔和/或切割和连接运营商,在赫尔维茨τ函数方法的结理论的精神,但这仍然是一个主题,为未来的调查。

英文摘要:

We investigate possibilities of generalizing the TBEM eigenvalue matrix model, which represents the non-normalized colored HOMFLY polynomials for torus knots as averages of the corresponding characters. We look for a model of the same type, which is a usual Chern-Simons mixture of the Gaussian potential, typical for Hermitean models, and the sine Vandermonde factors, typical for the unitary ones. We mostly concentrate on the family of twist knots, which contains a single torus knot, the trefoil. It turns out that for the trefoil the TBEM measure is provided by an action of Laplace exponential on the Jones polynomial. This procedure can be applied to arbitrary knots and provides a TBEM-like integral representation for the N=2 case. However, beyond the torus family, both the measure and its lifting to larger N contain non-trivial corrections in \hbar=\log q. A possibility could be to absorb these corrections into a deformation of the Laplace evolution by higher Casimir and/or cut-and-join operators, in the spirit of Hurwitz tau-function approach to knot theory, but this remains a subject for future investigation.
