摘要
利用重合度理论中的延拓定理和Lyapunov泛函方法讨论了一类具有多个滞量的多物种生态竞争系统周期正解的存在性和全局吸引性,得到了一些新的结果.实例表明我们的结果更加广泛,更加便于应用.
With the help of continuation theorem in conincidence degree theory andLyapunov funcitonal, we study existence and global attractivity of positive periodicsolution of multispecies ecological competition system with several delays. Some newresults are obtained. Example shows that our results are more general and more easilyverifiable.
