Description
Carrollian physics has recently emerged as a powerful framework for describing gravitational subsystems with null boundaries, playing a central role in settings such as flat-space holography and black-hole horizons. In this talk, I will review the development of Carrollian structures, beginning with their algebraic formulation and then connecting it to the geometric viewpoint of null hypersurfaces in general relativity. The aim is to show that the Carrollian framework provides a natural and unifying language for the physics of null hypersurfaces.
