摘要

我们将 Aw-Rascle 模型的多维广义化与无压欧拉对齐系统进行了比较,在无压欧拉对齐系统中,通信权重是矩阵值。我们的广义模型包括非局部密度函数梯度形式的速度偏移,由与核 $K$ 的卷积给出。我们研究了这些模型在宏观、介观和宏观(流体力学)层面上的联系,并概述了对 $K$ 的各种假设下的均场极限结果。

Non-local dissipative Aw-Rascle model and its relation with Matrix-valued communication in Euler alignment
We compare the multi-dimensional generalisation of the Aw-Rascle model with the pressureless Euler-alignment system, in which the communication weight is matrix-valued. Our generalisation includes the velocity offset in the form of a gradient of a non-local density function, given by the convolution with a kernel $K$. We investigate connections between these models at the macroscopic, mesoscopic and macroscopic (hydrodynamic) level, and overview the results on the mean-field limit for various assumptions on $K$.
