一类具多时滞和脉冲Lotka-Volterra 竞争系统的正周期解
Positive Periodic Solutions of a Lotka-Volterra Competition System with Impulses and Several Delays
摘要
Abstract
A non automomous periodic Lotka-Volterra competition system with impulses and several delays is investigated. By means of coindence degree theory and some analysis techniques, we obtain that the impulses will influence on the existence of positive periodic solutions of the system. Moreover, we deduce some new criteria for the existence of positive periodic solutions of the two-species comptition system with delays studied by Fan Meng, et al and Li Mei-li, et al respectively, our results improve and give some supplement for those obtained by research of Fan Meng, et al and Li Mei-li, et al.关键词
