Résumé : The connections between the su(2) deformations sur(2) and sup,q(2) (where r = √pq) are re-examined. Although the sup,q (2) coproduct truly depends on both parameters p and q, the Wigner and Racah coefficients are identical for both algebras. Explicit expressions for those of sup,q(2) are given in terms of p and q. © 1993.
