Periodic solution for a delayed three-species food-chain system with Holling type-II functional response. (English) Zbl 1055.34134

The authors study population dynamics taking into account the seasonality of the changing environment and the effect of time delay. They propose sufficient conditions for the existence of positive periodic solutions to the governing system of delay-differential equations.
