The Chebyshev-Boubaker polynomials are the orthogonal polynomials whose coefficient arrays are defined by ordinary Riordan arrays. Examples include the Chebyshev polynomials of the second kind and the Boubaker polynomials. We study the connection coefficients of this class of orthogonal polynomials, indicating how Riordan array techniques can lead to closed-form expressions for these connection coefficients as well as recurrence relations that define them.
切比雪夫 - 布贝克多项式是其系数阵列由普通里奥丹阵列定义的正交多项式。例子包括第二类切比雪夫多项式和布贝克多项式。我们研究这类正交多项式的连接系数,展示里奥丹阵列技术如何能得出这些连接系数的封闭形式表达式以及定义它们的递推关系。
