Existence of periodic solution of Nicholson-type system with nonlinear density-dependent mortality

Abstract

This article studies an $\omega$-periodic system of Nicholson-type differential equations with nonlinear density-dependent mortality rate. Using the degree theory we obtain sufficient conditions for the existence of a positive solution $\omega$-periodic. Our result complement previous researches on the subject.
