摘要 借助差分不等式,研究一类具Beddington-DeAngelis功能反应和反馈控制的离散非自治竞争系统的持久性,得到了一组新的持久性条件,从而改进了已有的工作。数值模拟验证了结果的可靠性。 We consider a discrete nonautonomous competitive system with Beddington-DeAngelis functional response and feedback controls. Using difference inequality theory, new conditions on permanence of the system are obtained. The results improve the recent one obtained by Zhang Jiehua. The numerical simulations show the feasibility of our results.
