【摘要】 研究具有反馈控制变量的时滞离散单种群模型的持久性问题,得到了一组新的保证该系统持久的充分性条件.所得结果实质性的改进了吴丽萍[具有反馈控制和时滞的"食物有限"离散种群模型的持久性]一文的主要结果.更多还原

【Abstract】 The persistent problems of delay discrete single model with feedback control variable is discussed and a new set of sufficient condition which guarantees the permanence of the system is obtained.Our result improves the main result of Wu Liping’s paper [permanence of the "food limited" discrete population model with feedback control and delay].更多还原
