Abstract
We investigate N-point string scattering amplitudes in AdS3 space. Based on recent observations on the solutions of KZ and BPZ-type differential equations, we discuss how to describe the string theory in AdS3 as a marginal deformation of a (flat) linear dilaton background. This representation resembles the called “discrete light-cone Liouville ” realization as well as the FZZ dual description in terms of the sine-Liouville field theory. Consequently, the connection and differences between those and this realization are discussed. The free field representation presented here permits to understand the relation between correlators in both Liouville and WZNW theories in a very simple way. Within In this paper we study a representation of the N-point correlation functions describing string scattering amplitudes in Euclidean AdS3. The tree-level amplitudes of strings in this space were extensively studied in the literature and received renewed attention since the formulation of the AdS/CFT correspondence. The first exact computation of three and two-point functions
