Big q-Jacobi polynomials

In mathematics, the big q-Jacobi polynomials P_n(x;a,b,c;q), introduced by (Andrews Askey), 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 basic hypergeometric functions by

[math]\displaystyle{ \displaystyle P_n(x;a,b,c;q)={}_3\phi_2(q^{-n},abq^{n+1},x;aq,cq;q,q) }[/math]
