這篇論文主要是在研究線性化波茲曼方程的譜分析以及長時間的行為。首先,我們先了解波茲曼方程以及波茲曼碰撞算子。接著,我們進一步了解波茲曼方程的一些性質。第二,我們探討線性化波茲曼方程以及它的一些性質。藉由線性化波茲曼方程的初始值問題的解,我們更進一步研究譜分析。最後,我們估計線性化波茲曼方程長時間的衰退率。
This thesis aims to investigate the spectrum analysis and the large time behavior of the linearized Boltzmann equation. First, we realize the Boltzmann equation and
the Boltzmann collision operator. And then, we further realize some properties of the Boltzmann equation. Second, we explore the linearized Boltzmann equation and its some properties. From the global solution for the initial value problem of the linearized Boltzmann equation, we further investigate the spectrum analysis. Last, we estimate the large-time decay rates of the linearized Boltzmann equation.
