Abstract  

Since string theory on AdS₃ with NSNS-flux is solvable in principle, AdS₃/CFT₂ correspondence with the string theory is expected to be useful for studying the general properties of holographic principle. Recently, it was claimed that string theory on AdS₃ x X with NSNS-flux is dual to a symmetric orbifold M^N/S_N with a marginal deformation. Here the seed theory M consists of linear dilaton and CFT₂ describing X. In this talk, I will derive the AdS₃/CFT₂ correspondence by applying recent discussion on the moduli localization of string amplitudes and CFT₂ technique we developed to prove Fateev-Zamolodchikov-Zamolodchikov duality.
