摘要
本文考虑色噪声做为一个新的变量,利用类WKB方法得到了由OU色噪声驱动的布朗粒子所满足的三維FPE的定态几率密度。
The probability density of Brownian particle driven by Ornstein-Uhlcnbeck (OU) colored noise obeys a three-dimensional Fokker-Planck equation (FPE), if we consider colored novsc as a new variable. We obtain the stationary solution of the FPE by using like-WKB method.
