Résumé :

q-analogues of the Perelomov coherent states are defined for suq(2) and they are shown to satisfy a unity resolution relation. The suq(2) matrix representations are reconstructed from the q-coherent state representation by a q-analogue of K-matrix theory. The q-analogues of the Dyson and Holstein-Primakoff su(2) boson realizations are also obtained. © 1991.
