Vlasov-Poisson-Boltzmann系统的谱分析

Spectrum analysis for the Vlasov-Poisson-Boltzmann system

Hailiang Li, Tong Yang, Mingying Zhong

摘要:

通过确定一个范数来描述由泊松方程控制的强迫效应,我们给出了线性化Vlasov-Poisson-Boltzmann系统在全局Maxwell附近的详细谱分析.结果表明,自洽的泊松方程所支配的电场在分析中起着关键作用,从而使谱结构真正不同于众所周知的玻尔兹曼方程。在此基础上,我们给出了平衡点解的最优时间衰减率。

英文摘要:

By identifying a norm capturing the effect of the forcing governed by the Poisson equation, we give a detailed spectrum analysis on the linearized Vlasov-Poisson-Boltzmann system around a global Maxwellian. It is shown that the electric field governed by the self-consistent Poisson equation plays a key role in the analysis so that the spectrum structure is genuinely different from the well-known one of the Boltzmann equation. Based on this, we give the optimal time decay rates of solutions to the equilibrium.
