Abstract

We analyze in-in correlators and the wave function of the universe in dS. We compute loop integrals of in-in correlators in dS for scalars and comment on the nature of the functions encountered, a simplicity observerd compared to loops of wave functions, and find a new integral representation for in-in correlators. Since the wave functions are equivalent to AdS correlators by analytic continuation, this analysis is also valid for correlators in AdS.
