一类非线性周期时滞人口模型的全局渐近稳定性

ON GLOBAL ASYMPTOTIC STABILITY FOR A NONLINEAR PERIODIC DELAY POPULATION MODEL

通过对解的上下界估计，建立了一类非线性周期时滞人口模型的唯一正周期解全局渐近稳定的充分条件，补充了ＬａｌｉＢＳ和ＺｈａｎｇＢＧ并改进了ＫｕａｎｇＹ中相应的结果。

In this paper, the sufficient condition of global asymptotic stability of periodic unique positive solution for a nonlinear periodic delay population model is established by using estimates for upper and below boundary of the solution. It added Lalli B S and Zhang B G′s, and improved Kuang Y's corresponding produce.
