Positive Periodic Solutions for an Impulsive Ratio-dependent Predator-prey System with Delays
نویسندگان
چکیده
In this paper, we study a periodic ratio-dependent predator-prey system of two species with impulse and multiple time delays. By means of analysis techniques and the continuation theorem of coincidence degree theory, we obtain sufficient conditions for the existence of positive periodic solutions of the system. Our results extend previous results obtained in [9].

A Delayed Ratio-dependent Predator-prey System with Stage-structured and Impulsive Stocking on Predator
In this paper, a delayed ratio-dependent Holling-III predator-prey system with stage-structured and impulsive stocking on predator and continuous harvesting on prey is considered. We obtain sufficient conditions of the global attractivity of prey-extinction periodic solution and the permanence of the system. These results show that the behavior of impulsive stocking on predator plays an importa...
