摘要：
We describe the q-deformations of the realisations of the conformal algebra depending on the conformal dimension parameter-DELTA. The particular role of the conformal dimensions DELTA = 0, 1/2, 1 is pointed out. The q-deformed central extension terms, describing q-deformation of the Virasoro algebra, are derived. In the limit q --> 1 one obtains the usual central term. The transformation properties of the q-deformed energy-momentum tensor (DELTA = 2) consistent with the q-deformed central extension term are described.
