本文研究空间均匀的Fokker-Planck-Boltzmann方程.对满足质量和动量守恒以及能量线性增长的解,给出了其在任何时间区间[δ,T]包含(0,∞)上的加权L^1和L^2估计,利用这些结果以及碰撞算子已知的L^p和Sobolev估计,我们建立了方程解的光滑性和唯一性。
This paper is devoted to studying the spatially homogeneous Fokker-Planck Boltzmann equation. For solutions satisfying conservation of mass and momentum, and linear increasing of energy, new weighted L1 and L2 estimates on any time interval [δ,T] belong to (0, ∞) are given. With these results and the known/2 and Sobolev estimates of the collision operator, we establish the smoothness and uniqueness of the solutions of the equation.
