Title: Different perspectives on AdS3/CFT2 holography

Abstract: I will discuss AdS3/CFT2 holography from the two perspectives of integrability and worldsheet CFT and comment on their relations and recent progress.  I will describe the integrable structure of the stringy Wess-Zumino-Witten models arising in AdS3/CFT2 and obtain a solid link between the integrability and worldsheet CFT approaches to this duality. Moreover, from the worldsheet CFT perspective, I will show how some three-point functions can be explicitly derived and matched on the two sides of the duality.  This amounts to one of the very first holographic matches of non-protected AdS3/CFT2 correlators.
