Abstract
- By using the continuation theorem base on Gaines and Mawhin''s coincidence degree, sufficient and realistic conditions are obtained for the global existence of positive periodic solutions for a discrete time nonautonomous food chain model, and sufficient conditions for the global stability of positive periodic solutions are also obtained. Some known results are extended. [Copyright &y& Elsevier]
