摘要
研究了一类含有多个时滞的脉冲微分方程.在系数变号的情形下,利用锥上的不动点定理获得了其正ω-周期解的存在性结果,并讨论了生态数学中所提出的几类时滞脉冲微分方程模型.
A kind of impulsive differential equations with delays are studied,and positive periodic solutions are obtained by applying fixed point theorems on cone under the condition of coefficient changing sign.And impulsive differential equations applied to biological system are also discussed.
