摘要
考察一类具多时滞的离散Lotka-Volterra互惠模型.利用迭代理论、M—矩阵理论、单调理论,分析该系统的持久存在性和吸引性,得到了该差分系统一致持久存在和其正解全局吸引的充分条件.
In this paper, we investigate a class of discrete - time Lotka - Volterra facultative mutualism system with different delays. By using the iteration method , M -matris theory and monotonous theory, the sufficient conditions are obtained for global attractivity and boundedness and persistence of positive solutions of this difference system.
