Title: Relativistic imperfect fluids
Abstract: In this talk I will explain the simple relativistic fluid in the presence of dissipation. The goal is to construct a gradient order expansion of the current and energy momentum tensor in Eckart frame using the entropy production argument. Entropy constraints on dissipative fluids come from the generalization of the second law of thermodynamics and imply that the hydrodynamic transport coefficients are positive definite.
