Description
Causality imposes subtle constraints on the coupling
constants in effective field theory. If the constraints are
violated, then the theory cannot be UV completed. I will
describe analogous causality constraints in strongly coupled
conformal field theory using the conformal bootstrap. I will
also discuss the consequences for the dual gravitational
action, and progress towards a direct derivation of Einstein
gravity 3-point couplings from CFT.
