Periodic solution to a delayed predator-prey system with stage structure and dispersion. (English) Zbl 1249.34241
Summary: A delayed two-species predator-prey system with stage structure and diffusion is investigated. Based on the continuation theorem of coincidence degree theory, sufficient conditions for the existence of positive \(\omega\)-periodic solution to the system are derived. A numerical simulation of an example illustrates our main result.
