Stochastic Perturbation Dynamic Behavior Analysis of Additional Food Provided Predator-prey System
摘要
Abstract
We consider an additional food provided predator-prey system with stochastic perturbation. There exists a unique positive solution of the system with positive initial value, and the existence of the stochastic model stationary distribution is proved. Moreover, the conditions for the system to be extinct are given and the conclusions are verified by numerical simulation.关键词
