Abstract: By using the continuation theorem of coincidence degree, the existence of positive periodic solution for three-species model with HollingⅢ type functional response was studied. The sufficient conditions of the existence of periodic solutions were obtained.
Key words: HollingⅢ type functional response; periodic solution; continuation theorem
