Positive periodic solutions in generaliz
✍ Xiaoquan Ding πŸ“‚ Article πŸ“… 2008 πŸ› Elsevier Science 🌐 English βš– 170 KB

By using a continuation theorem based on coincidence degree theory, we establish easily verifiable criteria for the existence of periodic solutions in generalized ratio-dependent predator-prey systems. Some known results are shown to be special cases of the presented paper.

A set of easily verifiable sufficient conditions is derived for the global existence of periodic solutions with strictly positive components for a periodic predator-prey system with infinite delays by using the method of coincidence degree.
