椭圆量子代数$U_{q,p}(\hat{sl_N})$及其顶点算子

The elliptic quantum algebra $U_{q,p}(\hat{sl_N})$ and its vertex operators

Wen-Jing Chang, Xiang-Mao Ding

摘要:

我们构造了椭圆量子代数$U_{q,p}(\hat{sl_N})$的一个实现,它是用自由玻色子场和它们的扭曲伙伴来表示的,对于任意给定的能级$k$。它可以看作量子仿射代数$U_{q}(\hat{sl_N})$的Wakimoto实现的椭圆变形。我们还构建了一个家庭的筛选电流,与$U_{q,p}(\hat{sl_N})$的电流交换总q差。通过扭曲量子仿射代数$U_{q}(\hat{sl_N})$的$I$型顶点算子的已知结果和本文得到的$U_{q}(\hat{sl_N})$的$II$型顶点算子的新结果,给出了$U_{q,p}(\hat{sl_N})$的$I$型和$II$型顶点算子的显式扭曲表达式.

英文摘要:

We construct a realization of the elliptic quantum algebra $U_{q,p}(\hat{sl_N})$ for any given level $k$ in terms of free boson fields and their twisted partners. It can be considered as the elliptic deformation of the Wakimoto realization of the quantum affine algebra $U_{q}(\hat{sl_N})$. We also construct a family of screening currents, which commute with the currents of $U_{q,p}(\hat{sl_N})$ up to total q-differences. And we give explicit twisted expressions for the type $I$ and the type $II$ vertex operators of $U_{q,p}(\hat{sl_N})$ by twisting the known results of the type $I$ vertex operators of the quantum affine algebra $U_{q}(\hat{sl_N})$ and the new results of the type $II$ vertex operators of $U_{q}(\hat{sl_N})$ we obtained in this paper.
