Abstract
In this paper, we consider certain first-order neutral differential system with two parameters. Some existence results of one positive periodic solution and two positive periodic solutions and nonexistence of positive periodic solutions are obtained. Our approach is based on Krasnoselskii fixed point theorem in cones.
