Relativistic Liquids: GENERIC or EIT?

Understand

We study the GENERIC hydrodynamic theory for relativistic liquids formulated by Ottinger and collaborators.

• We use the maximum entropy principle to derive its conditions for linear stability (in an arbitrary reference frame) and for relativistic causality.
• In addition, we show that, in the linear regime, its field equations can be recast into a symmetric-hyperbolic form.
• Once rewritten in this way, the linearised field equations turn out to be a particular realization of the Israel-Stewart theory, where some of the Israel-Stewart free parameters are constrained.
