Hidden symmetry of Hahn problem for $sl_q(2)

  title={Hidden symmetry of Hahn problem for \$sl\_q(2)},
A special case of Askey-Wilson algebra $AW(3)$ with three generators is shown to serve as a hidden symmetry algebra underlying the Hahn problem for the quantum algebra $sl_q(2)$. On the base of this hidden symmetry the corresponding Clebsch-Gordan coefficients in terms of the q-Hahn polynomials is found.
