Abstract

We compute the worldsheet sphere partition function of string theory on global AdS 3 with pure NS-NS flux.Because of an unfixed Möbius symmetry on the worldsheet, there is a cancellation of infinities and only a part of the answer is unambiguous.We show that it precisely reproduces the holographic Weyl anomaly and the ambiguous terms correspond to the possible counterterms of the boundary CFT.
