摘要
利用微分不等式,构造李亚普诺夫泛函及Lyapunov-Razumikin Type定理,得到了具有离散时滞的非自治的两种群竞争模型的持续生存条件及正周期解存在且全局渐近稳定的充分条件．
in this paper, A nonautonornous Two- species competition model with discrete delays is studied. It is shown that model is uniform persistence under some appropriate conditions and sufficient conditionl are established the existence of a positive periodic solution which is globally asymptotically stable by differential inequality and lyapunov functional.
