On the Connection Coefficients of the Chebyshev-Boubaker Polynomials

الملخص EN

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.
