Abstract: | By means of the k-order q-boson realizations of suq(1,1), a new kind of q-coherent states, the two-variable coherent states, are introduced for the quantum algebra suq(l,1).They are relative to a definite irreducible representation of suq(1,1) and shown to satisfy a completeness relation in a subspace of q-boson's Fock space. With the help of these coherent states the z-representation, representation in functional space, for suq(1,1) is also discussed. |
