Abstract
Carrollian holography aims to provide a holographic description of quantum gravity in asymptotically flat spacetimes, in terms of a novel kind of ‘carrollian’ conformal field theory defined on the spacetime null conformal boundary 
. The goal of these lectures is to propose a self-contained, pedagogical introduction to this active field of research. The main focus is given to the correspondence between massless scattering amplitudes, including gravitational amplitudes, and correlators in Carrollian conformal field theory. Strong emphasis is put on the development of Carrollian conformal field theory as an intrinsic, independent, and non-perturbative framework in which to formulate gravitational scattering theory.
Based on Lectures given at Université Libre de Bruxelles during the Doctoral Solvay School, October 2025.
