Abstract

We provide an algebraic interpretation for two classes of continuous qq-polynomials. Rogers' continuous qq-Hermite polynomials and continuous qq-ultraspherical polynomials are shown to realize, respectively, bases for representation spaces of the qq-Heisenberg algebra and a qq-deformation of the Euclidean algebra in these dimensions. A generating function for the continuous qq-Hermite polynomials and a qq-analog of the Fourier-Gegenbauer expansion are naturally obtained from these models.
