The present paper is directed toward the study on the global attractivity of a unique positive periodic solution of a discrete hematopoiesis model with unimodal production functions and several time delays. This model is described by a nonlinear difference equation. The result obtained is proved by transforming this model into another difference equation and by using the Schauder fixed-point theorem.

一阶非线性时滞差分方程唯一正周期解的全局吸引力

本文旨在研究具有单峰生产函数和几个时间延迟的离散造血模型的唯一正周期解的全局吸引力。该模型由非线性差分方程描述。通过将该模型转化为另一个差分方程并利用Schauder不动点定理证明了所得结果。
