Multiple periodic solutions of a delayed predator-prey system with stage structure for the predator. (English) Zbl 1205.34111

Summary: By using the continuation theorem of coincidence degree theory, the existence of multiple positive periodic solutions for a delayed predator-prey system with stage structure for the predator is established.
