A generalization of entropy to near-equilibrium phenomena is provided by the
notion of a hydrodynamic entropy current. Recent advances in holography have led to
the formulation of fluid-gravity duality, a remarkable connection between the
hydrodynamics of certain strongly coupled media and dynamics of higher dimensional
black holes. This talk introduces a correspondence between phenomenologically defined
entropy currents in relativistic hydrodynamics and “generalized horizons” of
near-equilibrium black branes in a dual gravitational description. The event and
apparent horizons in the geometry of fluid-gravity duality are just particular
incarnations of this notion.
