An exact AdS/CFT duality, Matthias Gaberdiel, ETH Zurich
String theory on AdS3 x S3 x T4 with one unit of NS-NS flux is argued to be exactly dual to the symmetric orbifold of T4 in the large N limit. The string theory background can be described in terms of a solvable world-sheet theory. This allows one to compute the complete single-string spacetime spectrum and thereby demonstrate that it agrees with that of the symmetric orbifold of T4. Furthermore, the structure of the symmetric orbifold correlators can be reproduced from the world-sheet perspective. I will finally also explain how the world-sheet theory can be reconstructed from the symmetric orbifold theory in a Gross-Mende like limit.
