q-Charlier polynomials

In mathematics, the q-Charlier polynomials^[1] are a family of basic hypergeometric orthogonal polynomials in the basic Askey scheme. Roelof Koekoek, Peter A. Lesky, and René F. Swarttouw (2010, 14) give a detailed list of their properties.

Definition[]

The polynomials are given in terms of the basic hypergeometric function by

\displaystyle C_{n}(q^{-x};a;q)={}_{2}\phi _{1}(q^{-n},q^{-x};0;q,-q^{n+1}/a).

Orthogonality[]

Recurrence and difference relations[]

Rodrigues formula[]
