一类单种群动态模型的稳定性

摘要

In this paper,the author considers the asymptotic stability in a class single species dynamics model of the form N（t）＝N（t）[a＋βN（t一t1）－rNt（t—t2）］,（1） where β∈R， a、r∈（0,∞）,t1,t2∈ L0,∞),and the author obtained sufficient condition for positive constant equilibrlum N of（1） is asymptotically stable.
