Abstract
In this paper, we study the existence of positive periodic solutions for a predator-prey system with Smith Growth for prey, with stage structure and non-monotonic functional response for predator. Two bounded open sets are obtained by using analytic technique. By means of the continuation theorem based on coincidence degree theory, a set of sufficient conditions for this system to have at least two positive periodic solutions is obtained, which improve some known results.
