Stage-structured hematopoiesis model with delays in an almost periodic environment

Abstract In this article, we focus on stage-structured hematopoiesis model with time-dependent delays in an almost periodic environment. A threshold dynamic is characterized by basic reproduction ratio R 0 . By making use of skew-product semiflow approach, we show that the population is extinct if R 0 1 . The existence of a unique positive almost periodic solution is derived when R 0 > 1 , meanwhile, the global stability of the solution is verified under weaker conditions.
