摘要
Abstract
The effects of correlated noises on the Logistic growth system of tumor cell are investigated in this paper. We derive the approximate Fokker-Planck equation and analyze the effects of correlated parameters on steady-state probability distribution and mean first passage time. We find that the correlation time and colored noise intensity play an opposite role in determining the steady-state probability distribution. The mean first passage time increases with the incretion of correlation time and decreases with the incretion of multiplicative noise intensity and strength of colored cross correlation. Thus we can control the extinction velocity of abnormal cell by changing the multiplicative noise intensity.关键词
