Abstract
We associate a family of Hilbert spaces H q 2;λ(D) of analytic functions on the unit disk D=z∈\(\mathbb{C}\):|z|<1 the q-continuous Gegenbauer polynomials C n λ(x;q) on the interval]−1;1[ and give a q-analogue of the unitary integral transform that Watanabe constructed from the Hilbert space L 2(]−1;1[;(1−x 2)λ− \(\frac{1}{2}\)dx onto the weighted Hilbert space H 2;λ(D).
