本文研究了一类多时滞带反馈的非自治单种群模型正解的持久性,得到了以积分形式描述的很弱的持久性的充分条件,这是一个新的结果。
In this paper, we study the permanence of positive solutions for a class of nonautonomous single-species systems with time-varying delays and feedback controls. Some new criteria on the permanence is obtained under the rather weak conditions which are described by integrable form.
