Black Brane Entropy and Hydrodynamics
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.
