摘要
本文通过构造持久性与绝灭性泛函去讨论具有时滞的种群动力系统模型中的持久性与非持久性。 作者在文中对二维的L-V系统,三维食物链与其它的具有时滞的系统给出了一些持久性与绝灭性泛函,从而也就判别了这些系统的持久性与非持久性。
In this paper by persistent and extinct functional the author disscused the persistence and the extinction for models of population dynamic systems with lags.In this paper the author gave some persistenct and extinct functionals for two di-mentional Lotka-Voltrra systems, three dimentional food chains and other systems with lags.
