$sl_q(2)的Hahn问题的隐对称性
Hidden symmetry of Hahn problem for $sl_q(2)
摘要:
具有三个生成元的Askey-Wilson代数$AW(3)$的一个特例被证明是量子代数$sl_q(2)$的Hahn问题的隐对称代数.基于这种隐对称性,找到了相应的q-哈恩多项式形式的Clebsch-Gordan系数。
英文摘要:
A special case of Askey-Wilson algebra $AW(3)$ with three generators is shown to serve as a hidden symmetry algebra underlying the Hahn problem for the quantum algebra $sl_q(2)$. On the base of this hidden symmetry the corresponding Clebsch-Gordan coefficients in terms of the q-Hahn polynomials is found.
