本文证明了一类Vlasov方程的平稳分布的测度扰动的稳定性结果。我们利用这个结果证明了这些定态分布的N粒子近似在N ~(1/8)阶时间尺度上是一致有效的,这比通常的logN尺度要长得多.我们也证明了类似的结果近似的二维欧拉方程的涡滴方法。
In this paper, we prove a stability result for measure perturbations of some class of stationary distributions of a Vlasov equation. We use this result to prove that theNparticles approximation of these stationary distributions is uniformly valid on a time scale of orderN1/8, which is much longer than the usual logNscale. We also prove similar results for the approximation of the two-dimensional Euler equation by the vortex blob method.
