Abstract:The predator-prey system with impulsive effect and non-monotone functional response is studied. By using the method of coincidence degree theory, sufficient conditions are obtained for the existence of two positive periodic solution.
Keywords:Impulsive effect  non-monotone functional responses predator-prey system  positive periodic solutions  coincidence degree
