Coupling coefficients for tensor product representations of quantum $\mathrm{SU}(2)$

Quantum Algebra 2018-02-07 v1

Abstract

We study tensor products of infinite dimensional representations (not corepresentations) of the SU(2)\mathrm{SU}(2) quantum group. Eigenvectors of certain self-adjoint elements are obtained, and coupling coefficients between different eigenvectors are computed. The coupling coefficients can be considered as qq-analogs of Bessel functions. As a results we obtain several qq-integral identities involving qq-hypergeometric orthogonal polynomials and qq-Bessel-type functions.
