摘要
对一类成虫竞争模型进行分析 ,得到了该模型在时滞τ充分小时解的有界性 ,以及各类平衡点存在的充要条件 ,并通过构造Liapunov泛函得到了平衡点局部稳定的充分条件和吸引域。
In this paper, by analyzing the competitive model of adult population, the solution boundedness of the model at time delay and the sufficient conditions of the existence of its various equilibrium points are obtained. Simultaneously the sufficient conditions and attractive regions of local steady of the equilibrium points are obtained by constructing Liapunov functional .
