我们使用底层 Fock 空间来表示仿射李代数 \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}\end{document} 构造一系列顶点运算符。作为一个应用,获得了由 2 个变量(或 3 个变量)的量子环面 ℂq 协调的 AN−1 型扩展仿射李代数的不可约模块。此外,该模块被证明是权重最高的模块,它是仿射李代数基本模块的模拟。
We use the underlying Fock space for the homogeneous vertex operator representation of the affine Lie algebra \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}\end{document} to construct a family of vertex operators. As an application, an irreducible module for an extended affine Lie algebra of typeAN−1coordinatized by a quantum torus ℂqof 2 variables (or 3 variables) is obtained. Moreover, this module turns out to be a highest weight module which is an analog of the basic module for affine Lie algebras.
