New results on the almost periodic solutions for a model of hematopoiesis with an oscillatory circulation loss rate

Abstract

This paper is concerned with a nonautonomous time-delayed model for the regulation of the hematopoiesis with an oscillating circulation loss rate. We prove a fixed point theorem in cones to establish some sufficient conditions ensuring the existence of positive almost periodic solutions of the model with almost periodic coefficients. Moreover, some examples are given to illustrate our theoretical results.
