Résumé |
I will discuss perturbative string theory on AdS3 with pure NS-NS flux and propose
a dual spacetime CFT. It is given by a symmetric orbifold of a linear dilaton
theory deformed by a marginal operator from the twist-2 sector. After explaining
the ingredients of the proposed duality in detail, I discuss the computation of
two- and three-point functions. The CFT results at large N agree with the string
computation at genus 0, thus providing ample evidence for a duality. I also show
how to match the full spectra of both short and long strings. |
