Existence of positive periodic solutions of competitor-competitor-mutualist Lotka-Volterra systems with infinite delays

Abstract

In this paper, the authors primarily explore a delayed competitor-competitor-mutualist Lotka-Volterra model, which is a system of differential equation with infinite integral. The authors first study the existence of positive periodic solutions of the model by using the Krasnoselskii’s fixed point theorem, and then present an example to illustrate the main results.
