  • 假設空間均勻分布的波茲曼方程有一存在於特定勒貝格積分空間的解,並利用二項式展開的類似手法對此解的矩作時間上的類指數估計。


    The thesis is divided into three parts. It includes a brief introduction of
    the collision kernel, and the uses of the tools in X. Lu, C. Mouhot, <On measure solutions of the Boltzmann equation, part I: moment production and stability estimates.> to derive
    the result for a solution of spatially homogeneous Boltzmann equation in
    Lebesgue p-integrable space with finite initial moment and makes it to be
    controlled by an exponentially like function as time goes on. And after the
    conclusion comes along some appendices which make the thesis more clear
    on its way to the final work.
