具有非Lipschitz力的相互作用粒子系统的平均场动力学方程

The Mean Field Kinetic Equation for Interacting Particle Systems with Non-Lipschitz Force

Qitao Yin, Li Chen, Simone Göttlich

摘要:

本文证明了由$N$ -粒子牛顿系统导出的平均场动力学方程弱解的整体存在性。对于$L^1\cap L^\infty$初始数据,平均场动力学方程的可解性可以通过统一估计和紧性参数来获得,而非局部非线性相互作用带来的困难则可以通过Aubin-Lions紧嵌入定理得到适当的解决。

英文摘要:

In this paper, we prove the global existence of the weak solution to the mean field kinetic equation derived from the $N$-particle Newtonian system. For $L^1\cap L^\infty$ initial data, the solvability of the mean field kinetic equation can be obtained by using uniform estimates and compactness arguments while the difficulties arising from the non-local non-linear interaction are tackled appropriately using the Aubin-Lions compact embedding theorem.
