AdS3/CFT2 at higher genus
Lorenz Eberhardt
Abstract
A bstract We continue our study of the worldsheet theory of superstrings on AdS 3 × S 3 × 𝕋 4 in the tensionless limit [1]. We consider the theory on higher genus surfaces. We give evidence that the worldsheet correlators localise on certain worldsheets that cover the boundary of AdS 3 holomorphically. This simplifies the string moduli space integral dramatically to a finite sum. This property shows that the higher genus corrections of the string worldsheet reproduce the structure of the 1/ N corrections in the dual symmetric orbifold CFT Sym N (𝕋 4 ).
