Positive periodic solutions of discrete n-species food-chain systems

Abstract

Discrete periodic n-species food-chain systems with Holling types II and III functional responses and time delays are investigated, respectively. By using Gaines and Mawhin s continuation theorem of coincidence degree theory sufficient conditions are obtained for the existence of positive periodic solutions of the systems. 2004 Elsevier Inc.
