[AnLy] Carrollian fluids and Chthonian versus celestial holography

Online seminar
Abstract: The usual approach of fluid/gravity correspondence coincides with solving Einstein's equations in a generalized "incomplete Newman-Unti gauge". In this framework, the asymptotic symmetry group is bigger and accounts for the boundary-fluid hydrodynamic frame invariance. The latter pattern holds both for Einstein and Ricci-flat spacetimes, dual to relativistic and Carrollian fluids, respectively. This is a concrete starting point for approaching flat holography and understanding the role of the BMS group on the dual boundary theory. It suggests that the latter might be non-local in order to account for the infinite Chthonian degrees of freedom, as opposed to the celestial proposal.
