The semiclassical limit of W_N. CFTs and Vasiliev theory

This work is a detailed study of the holographic duality between Vasiliev's higher spin theory and two-dimensional minimal model conformal field theories (CFTs) with WN symmetry. It uses symmetry arguments to identify the precise states dual to conical defects, correcting an earlier proposal, and to excitations of Vasiliev's scalar field. This work is important as it shows a highly nontrivial matching of the spectra of the CFT and Vasiliev's theory.
