Holographic entropy currents from AdS/CFT

Relativistic hydrodynamics has been the focus of significant interest in recent years due its successful application to heavy ion collisions. Since quark gluon plasma is strongly coupled in the applicable regime it is interesting to consider the hydrodynamics of N=4 supersymmetric Yang-Mills theory, where a calculable dual description exists and allows a derivation of the hydrodynamic framework. After some introductory review, I will discuss the construction of the hydrodynamic entropy current on both sides of AdS/CFT duality highlighting the question of ambiguities arising at second order in the gradient expansion.
