摘要

证明了一类具有修正版Leslie-Gower和holling型II型功能响应的非自治随机捕食-食饵模型的随机微分方程系统整体正解的存在唯一性,该模型受白噪声、中心泊松噪声和非中心泊松噪声干扰。得到了系统解的随机极限有界性、随机持久性、均值非持久性、均值弱持久性和消光性的充分条件。

Long-time behavior of a nonautonomous stochastic predator–prey model with jumps
It is proved the existence and uniqueness of the global positive solution to the system of stochastic differential equations describing a non-autonomous stochastic predator-prey model with a modified version of Leslie-Gower and Holling-type II functional response disturbed by white noise, centered and non-centered Poisson noises. We obtain sufficient conditions of stochastic ultimate boundedness, stochastic permanence, non-persistence in the mean, weak persistence in the mean, and extinction of the solution to the considered system.
