与$U_{q}(\widehat{sl_{n}})$相关的对称张量表示的$R$ -矩阵的构造

Construction of $R$-matrices for symmetric tensor representations related to $U_{q}(\widehat{sl_{n}})$

Gary Bosnjak, Vladimir V. Mangazeev

摘要:

本文对任意权的对称张量表示构造了与仿射代数$U_{q}(\widehat{sl_{n}})$相关的$R$ -矩阵的一种新的分解表示。利用三维方法,我们得到了$R$ -矩阵的矩阵元的显式公式,并给出了“扭曲”$R$ -矩阵是随机的一个简单证明.我们还讨论了$R$ -矩阵的对称性,它的退化,并比较我们的公式与文献中的其他结果。

英文摘要:

In this paper we construct a new factorized representation of the $R$-matrix related to the affine algebra $U_{q}(\widehat{sl_{n}})$ for symmetric tensor representations with arbitrary weights. Using the 3D approach we obtain explicit formulas for the matrix elements of the $R$-matrix and give a simple proof that a "twisted" $R$-matrix is stochastic. We also discuss symmetries of the $R$-matrix, its degenerations and compare our formulas with other results available in the literature.
