Knizhnik-Zamolodchikov equations and the analytic structure of strings in AdS$_3$
The pole structure of string correlators in AdS$_3$ encodes essential information about the AdS$_3$/CFT$_2$ duality. The corresponding residues for spectrally flowed three-point functions have been extracted from their exact expressions and shown to match the predictions of the holographic CFT. Away from the tensionles...
