DESCRIPTION:Classical gravity in (3+1)-dimensional asymptotically flat spa
 cetimes (AFS) admits an infinite-dimensional symmetry algebra. This algebr
 a is generated by modes of equal-helicity gravitons transforming in intege
 r highest-weight representations of the Lorentz group and can be related t
 o a w-infinity algebra appearing in 2-dimensional conformal field theory (
 CFT). I will review these ideas which are central in the quest to formulat
 e a holographic correspondence in asymptotically flat spacetimes. The main
  goal of the talk will be to explain how these structures appear in a flat
 -space (or Carrollian) limit of 3d CFTs dual to gravity in 4d AdS.&nbsp\;
