关于双物种 Vlasov-Poisson 系统 Landau 阻尼的一则注记

A note on Landau damping of two-species Vlasov-Poisson system

Renjun Duan, Zhiwen Zhang

AI总结:

本文借鉴 GNR 方法证明双物种 Vlasov-Poisson 系统的非线性 Landau 阻尼,处理有限电子质量与大离子质量情形,并改进 $G$-泛函为仅含一阶导数的 $L^{d+1}$ 范数。

摘要:

在本注记中,我们采用 Grenier、Nguyen 和 Rodnianski 在文献 \cite{GNR} 中提出的方法,在相空间 $\mathbb{T}^d_x \times \mathbb{R}^d_v$(维数 $d\geq 1$)中研究双物种 Vlasov-Poisson 系统的非线性 Landau 阻尼。主要目标有两个:一是将单物种情形推广到电子质量有限且离子质量足够大的双物种情形;二是修改 $G$-泛函,使其涉及 $L^{d+1}$ 而非 $L^2$ 中的范数,并且仅包含至多一阶导数。

英文摘要:

In this note we adopt an approach by Grenier, Nguyen and Rodnianski in \cite{GNR} for studying the nonlinear Landau damping of the two-species Vlasov-Poisson system in the phase space $\mathbb{T}^d_x \times \mathbb{R}^d_v$ with the dimension $d\geq 1$. The main goal is twofold: one is to extend the one-species case to the two-species case where the electron mass is finite and the ion mass is sufficiently large, and the other is to modify the $G$-functional such that it involves the norm in $L^{d+1}$ instead of $L^2$ as well as derivatives up to only the first order.
