具有概周期系数的三种群第Ⅱ类功能性反应的全局渐近稳定性

摘要

讨论了一类具有概周期系数的三种群第Ⅱ类功能性反应的模型,通过利用微分不等式及构造适当的李雅普诺夫函数获得了其存在全局渐近稳定性的概周期解的充分条件.%The type Ⅱ functional response of three-species model with almost periodic coefficients is discussed. Making use of the theory of differential inequality and constructing some suitable Lyapunov function obtain sufficient conditions that guarantee the existence of a global asymptotical stable almost periodic solution of the system.
