"Positive periodic solutions for a class of first-order iterative differential equations with an application to a hematopoiesis model"

Abstract

"In this paper, a first-order iterative functional differential equation is investigated. With the help of the Schauder’s fixed point theorem, we established some sufficient criteria that ensure the existence of positive periodic solutions. In addition, an application to three hematopoiesis models is also provided to corroborate the effeteness of our main findings. These last ones substantially enrich and complement some earlier works."
