摘要
利用微分不等式的技巧,通过构造适当的李亚普洛夫泛函,建立了一类非自治时滞蚊子种群模型解的吸引域,证明了解相互指数吸引的充分条件,获得了零解的指数吸引性,并利用计算机数值模拟验证了所得理论结果的正确性和有效性。
By using the technique of differential inequality and constructing an appropriate Lyapunov functional,the attraction domain of a class of non-autonomous mosquito population model with time delay is established.The sufficient conditions of exponential attraction between solutions are proved,and the exponential attraction of zero solution is obtained.The correctness and validity of the theoretical results in this paper are verified by computer numerical simulation.
