动力学Kolmogorov-Fokker-Planck方程的整体Schauder估计

Global Schauder estimates for kinetic Kolmogorov-Fokker-Planck equations

Hongjie Dong, Timur Yastrzhembskiy

摘要:

本文给出了动力学Kolmogorov-Fokker-Planck(KFP)方程在动力学Hölder空间中所有变量的全局Schauder型估计和唯一的可解性结果。首项系数在$x, v$变量中是Hölder连续的,并且仅在时间变量中是可测量的。我们的证明的灵感来自Campanato的方法Schauder估计,并不依赖于KFP算子的基本解的估计。

英文摘要:

We present global Schauder type estimates in all variables and unique solvability results in kinetic Hölder spaces for kinetic Kolmogorov-Fokker-Planck (KFP) equations. The leading coefficients are Hölder continuous in the $x, v$ variables and are merely measurable in the temporal variable. Our proof is inspired by Campanato's approach to Schauder estimates and does not rely on the estimates of the fundamental solution of the KFP operator.
