Laurent双正交多项式与Riordan阵列
Laurent Biorthogonal Polynomials and Riordan Arrays
摘要：
我们表明，洛朗双正交多项式的定义三项递归具有常数系数的系数阵列是Riordan阵列。对于每个这样的家庭劳伦双正交多项式，我们以自然的方式相关联的家庭的正交多项式。我们还将这些结果推广到广义正交多项式的概念，其递归依赖于三个参数。
英文摘要：
We show that Laurent biorthogonal polynomials whose defining three-term recurrence have constant coefficients have coefficient arrays that are Riordan arrays. For each such family of Laurent biorthogonal polynomials we associate in a natural way a family of orthogonal polynomials. We also extend these results to a notion of generalized orthogonal polynomials whose recurrence depends on three parameters.
