摘要：
A q-discretization of the Virasoro algebra is studied which reduces to the ordinary Virasoro algebra in the limit of q --> 1. This is derived starting from the Moyal bracket algebra, hence it is a kind of quantum deformation different from the quantum groups. A representation of this new algebra by using q-parametrized free fields is also given.
