摘  要:
研究了一类具有反馈控制的基于比率的非自治三种群捕食模型的渐近性,利用比较原理给出了模型持久生存的条件,通过构造Lyapunov函数方法,得到了相应的周期模型正解的存在惟一且全局渐近稳定性的充分条件,并举例说明定理的可实现性.

摘  要:
The asymptotic stability of three nonautonomous ratio-dependent predation systems with feedback controls is investigated.Sufficient conditions for the persistence are obtained with comparison theorem.When the system is a periodic system,sufficient conditions are derived that guarantee the existence,uniqueness and global asymptotic stability of the positive periodic solution with the method of constructing Lyapunov functions.
