A Gentle Introduction to the AdS3/CFT2 integrability.
The study of the AdS3/CFT2 correspondence by exact techniques saw many remarkable advances over the last few years. Until very recently, most results were obtained when holography is realised without any RR background fluxes, so that the strings can be easily described as a worldsheet CFT. In presence of RR fluxes, other approaches seem necessary, like worldsheet integrability.
A major new result in this direction is the derivation, for the first time, of the mirror thermodynamic Bethe ansatz (TBA) equations which describe the theory's spectrum in the presence of RR fluxes.
In this talk I will give a pedagogical introduction to the main challenges of AdS3/CFT2 holography and to the various ingredients that are needed to yield the mirror TBA equations and eventually the spectrum of generic (non-protected) string states. The talk is mostly based on recent work with Sergey Frolov.
