含时空依赖力的分数阶Fokker-Planck次扩散方程

Fractional Fokker-Planck Equations for Subdiffusion with Space-and-Time-Dependent Forces

B. I. Henry, T. A. M Langlands, P. Straka

摘要:

在一般的时空相关力场中,从幂律等待时间连续时间随机游动导出了分数阶Fokker-Planck方程.的控制方程是来自一个广义的主方程,并被证明是等价于一个从属的随机朗之万方程。

英文摘要:

We have derived a fractional Fokker-Planck equation for subdiffusion in a general space-and- time-dependent force field from power law waiting time continuous time random walks biased by Boltzmann weights. The governing equation is derived from a generalized master equation and is shown to be equivalent to a subordinated stochastic Langevin equation.
