Title: Causal Cosmological Bootstrap

Abstract: In recent years, there has been an increasing interest in the interplay between amplitudes and cosmological correlators, particularly in how amplitudes techniques can constrain cosmological correlators. In this talk, I will give an overview of the formalism of the wavefunction of the universe and how it relates to cosmological correlators. We will focus on how a new set of cutting rules, derived from causality, explains the analytic structure of wavefunction coefficients. These cutting rules further constrain the analytic structure of cosmological correlators, making explicit the absence of a particular kind of singularities. Finally, I will address future research in the rich interplay between amplitudes and cosmology.
