| Abstract: | 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. |
