Horizon symmetries, hydrodynamics, and chaos

It is well known that gauge symmetries may become genuine symmetries
at asymptotic boundaries of a given spacetime. Examples are the
Virasoro symmetry in asymptotically Anti-de Sitter spacetimes and the
Bondi-Sachs-Meisner (BMS) symmetry in asymptotically flat spacetimes.
More recently, it has been shown that stationary horizons also possess
an infinite amount of symmetries. However, their interpretation is
lacking. I will show in the context of holography how these horizon
symmetries can be interpreted as symmetries of a dual hydrodynamic and
maximally chaotic theory.
