考虑一维颗粒介质的非线性Fokker-Planck方程。这是热浴中近似弹性粒子系统的动力学近似。我们证明了齐次解在时间上渐近地趋向于一个唯一的非麦克斯韦平稳分布。
We consider a nonlinear Fokker-Planck equation for a one-dimensional granular medium. This is a kinetic approximation of a system of nearly elastic particles in a thermal bath. We prove that homogeneous solutions tend asymptotically in time toward a unique non-Maxwellian stationary distribution.
