Positive Periodic Solutions for a Ratio-dependent Leslie-type Predator-prey System

摘要：

By using a continuation theorem based on coincidence degree theory, we establish easily verifiable criteria for the existence of periodic solutions to a delayed ratio-dependent Leslie-type predatorprey system. In particular, some known results are shown to be special cases of the presented paper.
