Periodic solutions of a discrete time Lotka–Volterra type food-chain model with delays. (English) Zbl 1081.92043

Summary: A periodic discrete time three trophic level Lotka-Volterra type food-chain model is investigated. By using R. E. Gaines and J. L. Mawhin’s continuation theorem of coincidence degree theory [Coincidence degree, and nonlinear differential equations. (1977; Zbl 0339.47031)], sufficient conditions are derived for the existence of positive periodic solutions of the model.
