多种群生态竞争-捕食连续型时滞系统正周期解的存在性和全局吸引性

Existence and Global Attractivity of Positive Periodic Solution of Multispecies Ecological Competition-Predator Continuous Time Delay System

利用 L yapunov- Razumikhin理论 ,讨论一类具有周期系数和连续时滞的多种群生态竞争 -捕食系统 ,在一定的条件下 。

By employing the Lyapunov Razumikhin technique,we consider the existence,uniqe ness and global attractivity of positive periodic solution of multispecies ecological competition predator system with periodic coefficients and continuous time delay
