Résumé :

By enlarging the uq(n) q-algebra to uq(n)+uq(m) and considering double irreducible tensors, as well as coupled q-commutators, q-bosonic creation and annihilation operators satisfying simple hermiticity and q-commutation relations are constructed in a tensor product of m Fock spaces. They generalize the Pusz-Woronowicz operators, to which they reduce whenever m=1. Their relations with the Biedenharn-Macfarlane operators are also given.
