关于动力学Cucker-Smale模型中的强局部排列

On strong local alignment in the kinetic Cucker-Smale model

Trygve Karper, Antoine Mellet, Konstantina Trivisa

摘要:

在最近的两篇论文中,作者研究了具有强局部对准的动力学群集方程的弱解的存在性和流体动力学极限。在这些论文中,作为Motsch和Tadmor提出的对齐项的限制情况,引入强局部对齐项来模拟群集行为。在本文中,我们严格证明了这一限制,并表明所考虑的方程确实是一个极限的Motsch-Tadmor模型时,相互作用的半径为零。分析涉及速度平均引理和几个$L^p$估计。

英文摘要:

In two recent papers the authors study the existence of weak solutions and the hydrodynamic limit of kinetic flocking equations with strong local alignment. The introduction of a strong local alignment term to model flocking behavior was formally motivated in these papers as a limiting case of an alignment term proposed by Motsch and Tadmor. In this paper, we rigorously justify this limit, and show that the considered equation is indeed a limit of the Motsch-Tadmor model when the radius of interaction goes to zero. The analysis involves velocity averaging lemmas and several $L^p$ estimates.
