摘要 使用差分比较定理和迭代方法,研究反馈控制的离散型时滞多种群生物系统的持久性问题,获得了该系统持久性的充分条件,并对一个实例进行数值模拟,验证了结论的有效性. In this paper,by applying difference comparison theorem and some kind of iterative method,we have established sufficient conditions which guarantee the permanence of a discrete M-species biological system with delays and feedback controls.Moreover,an example along with its numerical simulation is employed to illustrate the effectiveness of the proposed result.
