-
摘要: 研究了一类具有放牧率及扩散的3种群概周期竞争模型,利用上、下解方法,Schauder不动点定理以及Lyapunov稳定性理论,得到了确保该模型空间齐次概周期解的存在性及稳定性的充分条件,推广了已有的相应结果.Abstract: Almost periodic solution of a three-species competition system with grazing rates and diffusions were investigated by using the method of upper and lower solutions,the Schauder fixed point theorem as well as Lyapunov stability theory.Sufficient conditions guaranteeing the existence and stability of the strictly positive space homogenous almost periodic solution of the system were obtained,and some known results were improved.
