Title: Bootstrapping Inflationary Correlators
Abstract: The central idea of the bootstrap philosophy is to constrain observables directly from consistency conditions alone, bypassing the intricacies of the Lagrangian formalism and Feynman diagrams. In this talk, I will adopt this viewpoint and describe a new approach to determine cosmological correlators, following a perspective familiar from the modern studies of scattering amplitudes. Specifically, I will describe the symmetries and singularities of correlators in slow-roll inflation, and explain how these principles can be used to fully determine the final answer without reference to bulk time evolution.
