摘要
本文考虑一类互助生志模型的渐近性质。在对平衡点集的某些特殊假定下,我们得到了关于系统的ω-极限集、几乎处处收敛性及持久共存性的一些令人满意的结果。本文的研究部分地由Hirsch关于单调系统的开创性论文及Selgradc关于正反馈系统的工作所提示。
In this paper we consider the asymptotic properties of a class of ecological models of cooperating species. Under some particular assumptions for equilibrium sets, we obtain some satisfactory results concerning ω-limit sets, convergence almost everywhere and persistence. The study of the paper is motivated, in part, by Hirsch's starting articles[3] [4] [5] on monotone systems, and by selgrade's paper [8] on positive feedback systems.
