Existence results for positive periodic solutions to first order neutral differential equations with distributed deviating arguments

Abstract

We take into account the first order nonlinear neutral differential equation with distributed deviating arguments. Using Krasnoselskii's fixed point theorem, we give some new criteria for the existence of positive periodic solutions to this equation. The theorems we have established are illustrated by an example.
