q-Deformation of SU(1,1) Conformal Ward Identities and q-Strings

  • André LeClair
Part of the NATO ASI Series book series (NSSB, volume 245)


We define a q-deformation of the SU(1, 1) Ward identities of 2d conformally invariant field theory based on the quantum SU(1,1) algebra. The deformation preserves the main properties of the conformai Ward identities, namely that the two and three point functions are completely determined. A connection with a q-deformation of the Veneziano amplitude is revealed.
