线性扰动随机SI系统的渐近行为
Asymptotic Behavior of Stochastic SI System with Linear Perturbation
【摘要】 用Laypunov泛函方法研究随机SI系统全局正解的存在唯一性、持久性或灭绝性以及在某些条件下的随机渐近行为.结果表明:随机SI系统具有平稳分布,体现了遍历性.
【Abstract】 We discussed the existence and uniqueness,persistence,extinction and asymptotic behavior of the globally nonnegative solution of the stochastic SI system under certain conditions with Lyapunov analysis method.The stochastic SI system possesses stationary distributions and is ergodicity.
