【摘要】 由于时标理论不仅能够统一连续和离散分析,而且也具有重要的应用价值,因此主要研究时标上一类具有反馈控制的人口模型.利用Krssnoselskii不动点定理,得到了此人口模型周期解的存在性与唯一性.更多还原

【Abstract】 Since time scale calculus is the unification of the theory of difference equations with differential equations and has important applications,this work deals with a kind of population model with feedback control on periodic time scales.By means of a fixed point theorem due to Krasnoselskii,sufficient conditions are obtained to guarantee the existence and uniqueness of periodic solutions for the above population model.更多还原
