[来自U_{q} gl(2)表示的Yang-Baxter方程的有色解]

[Colored solutions of Yang-Baxter equation from representations of U_{q}gl(2)]

[Pi-Gang Luan, H. C. Lee, R. B. Zhang]

摘要:

我们研究了多参数版本的$U_{q}gl(2)$的Hopf代数结构和最高权表示。明确给出了交换关系以及其他Hopf代数映射。我们表明,多参数的通用${\cal R}$矩阵可以直接构造为量子双缠绕,而不使用Reshetikhin的变换。一个有趣的特征自动出现在表征理论中:它可以分为两种类型,一种是一般的$q$,另一种是作为单位根的$q$。将表示理论应用于多参数泛${\cal R}$矩阵,得到了Yang-Baxter方程的标准和非标准色解$R(μ,ν; μ', ν')$.

英文摘要:

We study the Hopf algebra structure and the highest weight representation of a multiparameter version of $U_{q}gl(2)$. The commutation relations as well as other Hopf algebra maps are explicitly given. We show that the multiparameter universal ${\cal R}$ matrix can be constructed directly as a quantum double intertwiner, without using Reshetikhin's transformation. An interesting feature automatically appears in the representation theory: it can be divided into two types, one for generic $q$, the other for $q$ being a root of unity. When applying the representation theory to the multiparameter universal ${\cal R}$ matrix, the so called standard and nonstandard colored solutions $R(μ,ν; μ', ν')$ of the Yang-Baxter equation is obtained.
