The power collection method for connection relations: Meixner polynomials

Michael A. Baeder, Howard S. Cohl, Roberto S. Costas-Santos +1

We introduce the power collection method for easily deriving connection relations for certain hypergeometric orthogonal polynomials in the $(q -)$ Askey scheme. We summarize the full…

Zeros of polynomials orthogonal with respect to a signed weight

M. Benabdallah, M. J. Atia, R. S. Costas-Santos

In this paper we consider the polynomial sequence $(P_{n}^{α, q} (x))$ that is orthogonal on $[- 1, 1]$ with respect to the weight function $x^{2q+1}(1-x^{2})^α(1-x), α>-1, q\in \mathb…
