Description
Carrollian holography aims to express gravity in asymptotically flat space-time in terms of a dual Carrollian CFT living at null infinity. In this talk, I will review how Carrollian geometry arises at the conformal boundary of asymptotically flat spacetimes. I will then discuss some aspects of Carrollian holography and argue that this approach is naturally related to the AdS/CFT correspondence via a flat limit procedure. I will introduce the notion of Carrollian amplitude, which allows to encode massless scattering amplitudes into boundary correlators, and describe its connection to celestial amplitudes.
