Representations of quantum groups and a q-analogue of orthogonal polynomials

The Peter-Weyl theorem for SμU(2) of Woronowicz is shown in an explicit form and a q-analogue of certain orthogonal polynomials is realized as the spherical functions for SμU(2) On presente le theoreme de Peter-Weyl pour SμU(2) de Woronowicz, sous une forme explicite, et realise un q-analogue de certains polynomes orthogonaux comme fonctions spheriques pour SμU(2)
