Dynamical Analysis of Discrete Predator-prey Models with Delays

摘要：

This paper investigates the existence of periodic solutions for discrete predator-prey models with delays. Based on continuation theorem, new sufficient condition is derived on the existence of periodic solutions for discrete systems with preydependent and predatordependent functional response bounded by polynomials. Our results extend the existing results. Numerical example is used to illustate our result.
