具有毒素脉冲输入和干扰的非自治随机模型
A Research of Nonautonomous Stochastic Population Model with Pulse Input of Environment Toxin and Random Perturbation
摘要
Abstract
A nonautonomous stochastic population model with pulse input of environment toxin and ran-dom perturbation was proposed. By constructing comparison systems and utilizing comparison theorem of dif-ferential equation, the boundedness of expectation and global attractivity of the system were proved. The suf-ficient condition of non-persistence in the mean and persistence in the mean were established. Furthermore, some dynamic behaviors of the system were investigated.关键词
