具有离散变时滞的N种群非自治Lotka-Volterra竞争系统的有界性和持久性

摘要

讨论了具有离散变时滞的N种群非自治Lotka-Volterra竞争系统的动力学性质,运用反证法得到了系统在均值条件下的有界性和持久性.最后通过一个数值实例验证了方法的有效性.%The dynamical behaviors of nonautonomous Lotka-Volterra competitive system with JV-species and discrete variable delays are investigated in this article. The boundedness and permanence under average conditions are obtained by using reduction to absurdity. Finally, a numerical example is given to verify the results.
