Description
In this talk I will review recent efforts to put holographic correlators in maximally symmetric space-times on the same footings, upon analytic continuation to Euclidean AdS space. I will focus mainly on the dS example which played a key role for Cosmological Bootstrap. I will discuss in detail the analytic continuation introduced and how this continuation imply a map between perturbative expansion of in-in dS correlators and EAdS correlators, commenting also on their analyticity properties. Towards the end I will also close the circle mentioning some ongoing efforts to revisit celestial holography via hyperbolic EAdS and dS slicings.
