摘要
研究了一类多时滞非自治三种群捕食模型的持久性和全局渐近稳定性,分别利用比较原理和构造Lyapunov函数方法得到了模型持久生存与全局渐近稳定性的充分条件,并举例说明定理的可行性且利用Matlab绘出图像.
The Persistence and global stability of the nonautonomous three species predatorprey model with multi-delay is investigated,The sufficient conditions are obtained for the persistence of this model by using comparison theorem and the global asymtotic stability of the positive solution is derived by constructing Liapunov-type functions.Especially,theorems are realized by giving an example and picture is drawed by using software of matlab.
