Correlation Functions of Winding Strings in AdS3

We review certain results for amplitudes of spectral flowed operators in string theory on AdS3. We present the modified Knizhnik‐Zamolodchikov and null vector equations to be satisfied by correlators including w = 1 operators. We then discuss the three point function of two w = 1 and one w = 0 operators in the x‐basis, and perform a consistency check on the definition of the w = 1 operator. We finally exhibit the steps in the calculation of the winding conserving four point functions for operators in arbitrary spectral flowed sectors, both in the m‐ and x‐basis, under the only assumption that at least one of the operators is in the spectral flowed image of the highest weight discrete representation.
