Semiclassical Virasoro blocks from AdS3 gravity
Semiclassical Virasoro blocks from AdS3 gravity
We present a unified framework for the holographic computation of Virasoro conformal blocks at large central charge. In particular, we provide bulk constructions that correctly reproduce all semiclassical Virasoro blocks that are known explicitly from conformal field theory computations. The results revolve around the use of geodesic Witten diagrams, recently …
