内容摘要：We consider type IIB string theory on AdS₃ × S³×T⁴ in a large AdS radius expansion at arbitrary values of the relative RR and NS--NS fluxes. We develop a method for computing scaling dimensions in the dual CFT in this limit by combining a string field theory calculation, valid at finite quantized NS--NS flux but perturbative in RR flux, with a finite mixed-flux ansatz, which is constrained by worldsheet parity and motivated by classical string solutions. We apply the method to three families of states. In the pure-RR limit, our results agree both with a family of states computed using the world-sheet bootstrap and with another family computed using integrability.
