相关噪声诱导的食饵灭绝控制
Correlated noise induced control of prey extinction
摘要:
研究了关联高斯白噪声下唯象的两态捕食模型的定态性质。从相应的概率分布函数的Fokker-Planck方程出发,研究了概率分布函数的稳态解及其极值。我们表明,对于一个典型的值的噪声相关性有一个巨大的损失的双稳性,这反过来又防止了猎物种群灭绝。
英文摘要:
We study the steady state properties of a phenomenological two-state predator model in presence of correlated Gaussian white noise. Based on the corresponding Fokker-Planck equation for probability distribution function the steady state solution of the probability distribution function and its extrema have been investigated. We show for a typical value of noise correlation there is a giant loss of bistability which in turn prevents the prey population from going into extinction.
