摘要
讨论了一类多时滞带反馈控制的非自治单种群模型正解的灭绝性,得到了以积分形式描述的灭绝性的弱充分条件,并得出反馈控制对该种群的灭绝性是无害的。
Extinction of positive solutions for a class of nonautonomous single-species systems with multiple time-delays and feedback controls is considered.The rather weak sufficient conditions described by integrable form on the extinction are obtained,and the feedback controls are harmless for the extinction of species is found.
