论文摘要
发现新的约束，必须对以色列 - 斯图尔特样流体动力学理论具有远离平衡的因果关系。还出现了足以确保因果关系，局部存在和解决方案独特性的条件。考虑到散装和剪切粘度（零化学势），我们的结果始于完整的非线性状态，而没有任何简化的对称性或近平衡假设。我们的发现提供了远离平衡的流体动力学粘性校正大小的基本限制。
New constraints are found that must necessarily hold for Israel-Stewart-like theories of fluid dynamics to be causal far away from equilibrium. Conditions that are sufficient to ensure causality, local existence, and uniqueness of solutions in these theories are also presented. Our results hold in the full nonlinear regime, taking into account bulk and shear viscosities (at zero chemical potential), without any simplifying symmetry or near-equilibrium assumptions. Our findings provide fundamental constraints on the magnitude of viscous corrections in fluid dynamics far from equilibrium.
