论文摘要
在本文中,我们证明了合适的粒子系统向BGK模型的收敛性。更确切地说,我们考虑了一个相互作用的随机粒子系统,在该系统中,每个粒子都可以在该系统中立即在本地热量化。我们表明,在适当的缩放限制下,混乱的传播确实存在,并且一颗粒子分布函数会收敛到BGK方程的溶液。
In this paper we prove the convergence of a suitable particle system towards the BGK model. More precisely, we consider an interacting stochastic particle system in which each particle can instantaneously thermalize locally. We show that, under a suitable scaling limit, propagation of chaos does hold and that the one-particle distribution function converges to the solution of the BGK equation.
