Title:  Bulk locality from the conformal bootstrap

Abstract: 

The conformal bootstrap aims to calculate scaling dimensions and correlation functions of local operators in various theories, starting from general principles such as unitarity and crossing symmetry.  It turns out that, due to causality, operators are not independent of each other but organize into analytic functions of spin, and I will present a formula which quantifies the consequences of this fact.  When applied to large-N theories with a sparse spectrum, the formula automatically encodes the constraints from bulk causality, and determines the four-point function to match that from classical gravity.  Based on 1703.00278.
