Causality and Universality at Strong Coupling
Tom Hartman, Cornell University,

 Causality imposes constraints on the coupling constants in perturbative effective field theory, which have played a role in understanding scattering amplitudes, the a-theorem for renormalization group flows, and higher curvature corrections in quantum gravity. I will describe similar constraints on strongly interacting theories, then use them to derive the averaged null energy condition, and discuss the connection to emergent geometry and the Einstein equations at large N.
