A duality in string theory on AdS${}_3$

Indranil Halder, Daniel Louis Jafferis, David Kolchmeyer

We consider bosonic string theory on ${\text{AdS}}_3$ supported by Kalb-Ramond flux. It is well known that the ${\alpha }^{\prime }$ exact worldsheet theory is described by the $\text{SL(2,R)}$ WZW m…
