摘要
利用李雅普诺夫泛函方法和微分不等式技巧研究了一类具有时滞的非自治川崎病模型解的正性、有界性以及持久性。借此提出保证系统周期解的全局指数稳定的充分性判据,推广了已有文献的相应结果,并结合数值模拟验证了理论结果的正确性和有效性。
By using Lyapunov functional method and differential inequality technique,the positivity,boundedness and permanence of solutions for a class of non-autonomous Kawasaki disease model with time delay are studied.Based on this,a sufficient criterion to ensure the global exponential stability of the periodic solution of the system is proposed,which extends the corresponding results of the existing literature.The correctness and validity of the theoretical results are verified by numerical simulation.
