Abstract:
We investigate the q-deformed Virasoro algebra presented by Curtright and Zachos. After showing some new results on the central extension and the operator product expansion, we discuss the relation between the q-deformed Virasoro algebra and the Volterra Poisson bracket algebra. The realization in terms of an inifinite set of oscillators is also discussed from the viewpoint of a deformation of the Poisson bracket.
