A general organizing principle is proposed that can be used to derive the equations of motion describing the near-equilibrium dynamics of causal and thermodynamically stable relativistic systems. The latter are found to display some new type of universal behavior near equilibrium that allows them to be grouped into universality classes defined by their degrees of freedom, information content, and conservation laws. The universality classes expose a number of surprising equivalences between different theories, shedding new light on the near-equilibrium behavior of relativistic systems.
提出了一个通用的组织原则，可用于推导描述因果和热力学稳定相对论系统近平衡动力学的运动方程。发现后者在平衡附近表现出某种新型的普遍行为，这使得它们能够根据其自由度、信息内容和守恒定律被归类到不同的普适类中。这些普适类揭示了不同理论之间的一些惊人等效性，为相对论系统的近平衡行为提供了新的见解。
