Ultra-analytic effect of Cauchy problem for a class of kinetic equations

Yoshinori Morimoto, Chao-Jiang Xu

摘要:

研究了一类动力学方程柯西问题的光滑化效应。首先考虑空间齐次非线性Landau方程和非齐次线性Fokker-Planck方程的Cauchy问题的超解析效应。这些光滑效果的结果是最佳的,类似于热方程。在第二部分中,我们研究了一类具有Maxwell分子的空间非齐次线性Landau方程模型,并给出了Cauchy问题的解析解。

英文摘要:

The smoothing effect of the Cauchy problem for a class of kinetic equations is studied. We firstly consider the spatially homogeneous non linear Landau equation with Maxwellian molecules and inhomogeneous linear Fokker-Planck equation to show the ultra-analytic effects of the Cauchy problem. Those smoothing effect results are optimal and similar to heat equation. In the second part, we study a model of spatially inhomogeneous linear Landau equation with Maxwellian molecules, and show the analytic effect of the Cauchy problem.
