Almost Periodic Type Solutions For A Hematopoiesis Model

In this thesis, we discuss the existence and stability of almost periodic type solutions to a class of hematopoiesis models. The thesis is organized as follows.In Chapter 1, we introduce the backgrounds of the problem and the main results of this thesis.In Chapter 2, we establish the existence and stability of asymptotically almost periodic solution to a hematopoiesis model , x’(t)=-α(t)x(t)+(?),t∈R.We do not assume that (?)α(t) > 0, which is a key assumption in many related results.In Chapter 3, we discuss the the existence and stability of pseudo almost periodic solution to the above hematopoiesis model under the assumption that all coefficient functions are pseudo almost periodic.
