We provide a simple method to recognize a classical orthogonal polynomial sequence on a q-quadratic lattice defined only by the three-term recurrence relation. It is pointed out that this can be extended to all orthogonal polynomials in the q-Askey scheme.

关于正交多项式序列及其递推系数

我们提供了一种简单的方法来识别仅由三项递推关系定义的q二次晶格上的经典正交多项式序列。指出这可以扩展到q -Askey方案中的所有正交多项式。
