Worldsheet correlators in AdS3

I revisit the computation of string correlation functions in AdS3 from a worldsheet point of view. These correlators contain all the perturbative information about the spacetime CFT and the existence of winding strings in AdS3 makes them very rich. 

I will propose a full solution to the problem of computing these correlators. The winding correlators encode information about branched covering maps from the worldsheet to the boundary of the space. I will discuss the properties of the correlators in detail. In some limiting cases one can compute the full string correlators and compare them with the spacetime CFT.
