Title: A progress report on AdS3/CFT2 holography
Abstract: Quantitatively understanding strings on backgrounds supported by Ramond-Ramond fluxes is an open challenge in string theory. A perfect arena to make progress is that of AdS3 geometries, which can be supported by a combination of RR and NSNS fluxes; one may even start from better-understood NSNS backgrounds and gently switch on RR fluxes. I will review the recent (and not-so-recent) progress in this direction, obtained by a combination of integrability, worldsheet CFT and dual CFT techniques at various points of the moduli space, including at two distinct "tensionless" points.
There will be a student session at 13:00 before the talk.
