论文摘要
在本文中,我们研究了经典解决方案的扩散限制对弗拉索夫 - 波森 - 福克群 - 普朗克(VPFP)系统的扩散限,并在全球麦克斯韦安装附近具有初始数据。我们证明了基于光谱分析的融合,并建立了全局强溶液对VPFP系统的最佳收敛速率,以对频谱分析进行了解决方案。
In the present paper, we study the diffusion limit of the classical solution to the Vlasov-Poisson-Fokker-Planck (VPFP) system with initial data near a global Maxwellian. We prove the convergence and establish the optimal convergence rate of the global strong solution to the VPFP system towards the solution to the drift-diffusion-Poisson system based on the spectral analysis with precise estimation on the initial layer.
