Vlasov-Poisson系统的平均场极限

A mean field limit for the Vlasov-Poisson system

Dustin Lazarovici, Peter Pickl

摘要:

我们提出了一个概率证明的平均场的极限和传播的混沌$N$粒子系统在三维正(库仑)或负(牛顿)$1/r$潜力缩放像$1/N$和$N$依赖的截止像$N^{-1/3+ ε}$的规模。特别是,对于典型的初始数据,我们显示收敛的经验分布的Vlasov-Poisson系统的解决方案,无论是排斥性的电或吸引力的引力相互作用。

英文摘要:

We present a probabilistic proof of the mean field limit and propagation of chaos $N$-particle systems in three dimensions with positive (Coulomb) or negative (Newton) $1/r$ potentials scaling like $1/N$ and an $N$-dependent cut-off which scales like $N^{-1/3+ ε}$. In particular, for typical initial data, we show convergence of the empirical distributions to solutions of the Vlasov-Poisson system with either repulsive electrical or attractive gravitational interactions.
