On periodic solutions of Mackey-Glass hematopoiesis model via concave and increasing operator

Abstract

The paper is concerned with a Mackey-Glass hematopoiesis model. By em-ploying the fixed point theorem of u0 concave and increasing operator, we provide easily verifiable sufficient conditions for the existence of a unique positive periodic solution for the considered model. We provide numerical examples along with illustrative figures to demonstrate the theory. Our approach is new and it is different from previously considered methods.
