摘要
研究一类具有时滞和基于比率的三种群食物链捕食-被捕食动力学模型.证明了 该系统在适当条件下的一致持久性;通过构造Lyapunov泛函,得到了该系统正平衡点全 局渐近稳定的充分条件.
A three-species ratio-dependent predator-prey food Chain model with time delays is investigated. It is shown that the system is uniformly persistent under some appropriate conditions, and sufficient conditions are obtained for the global stability of the positive equilibrium of the system.
