DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AnLy/7/">Car
 rollian fluids and Chthonian versus celestial holography</a>\nby Marios Pe
 tropoulos (Ecole Polytechnique\, CPHT) as part of AnLy Strings and Fields 
 online seminars\n\n\nAbstract\nThe usual approach of fluid/gravity corresp
 ondence coincides with solving Einstein's equations in a generalized "inco
 mplete Newman-Unti gauge". In this framework\, the asymptotic symmetry gro
 up is bigger and accounts for the boundary-fluid hydrodynamic frame invari
 ance. The latter pattern holds both for Einstein and Ricci-flat spacetimes
 \, dual to relativistic and Carrollian fluids\, respectively. This is a co
 ncrete starting point for approaching flat holography and understanding th
 e 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 d
 egrees of freedom\, as opposed to the celestial proposal.\n
