$U_{v,t}(sl_{n})$的Schur-Weyl对偶

Schur-Weyl duality for $U_{v,t}(sl_{n})$

Yanmin Yang, Haitao Ma, Zhu-Jun Zheng

摘要:

在\cite{fl}中,作者得到了双参数量子代数$U_{v,t}(\mathfrak{g})$的一种新表示。他们的陈述可以涵盖所有Kac-Moody案件。本文构造了一个合适的Hopf对,使得$U_{v,t}(sl_{n})$可以实现为某些Hopf子代数关于该Hopf对的Drinfeld双.利用Hopf对,构造了$U_{v,t}(sl_{n})$的$R$ -矩阵,并利用它给出了$U_{v,t}(sl_{n})$与Hecke代数$H_{k}(v,t)$的Schur-Weyl对偶.此外,使用融合过程,我们构造的$H_{k}(v,t)$的本原正交幂等元。作为推论,我们给出了$V^{\otimes k}$的不可约$U_{v,t}(sl_{n})$ -表示的显式构造.

英文摘要:

In \cite{fl}, the authors get a new presentation of two-parameter quantum algebra $U_{v,t}(\mathfrak{g})$. Their presentation can cover all Kac-Moody cases. In this paper, we construct a suitable Hopf pairing such that $U_{v,t}(sl_{n})$ can be realized as Drinfeld double of certain Hopf subalgebras with respect to the Hopf pairing. Using Hopf pairing, we construct a $R$-matrix for $U_{v,t}(sl_{n})$ which will be used to give the Schur-Weyl dual between $U_{v,t}(sl_{n})$ and Hecke algebra $H_{k}(v,t)$. Furthermore, using the Fusion procedure we construct the primitive orthogonal idempotents of $H_{k}(v,t)$. As a corollary, we give the explicit construction of irreducible $U_{v,t}(sl_{n})$-representations of $V^{\otimes k}$.
