Positive Periodic Solution in a Delayed Predator-Prey System with Ratio-Dependence and Stage Structure for Predator

摘要：

By using a continuation theorem based on Gaines and Mawhins coincidence degree, we study the global existence of positive periodic solutions of a delayed predator-prey system with ratio-dependent functional response and stage structure for predator. A set of easily verifiable sufficient conditions are obtained, which improve some known results.
