Almost Periodic Type Solutions Of Nonlinear Difference Equations

In this thesis, we summarize almost periodic function, almost periodic sequence, pseudo almost periodic sequence and their qualities, and we also discuss the existence of almost periodic type solutions for nonlinear difference equation with delay.In chapter1, we introduce the backgrounds of the problem and the main results of this thesis.In chapter2, we investigate almost periodic function, almost periodic sequence, pseudo almost periodic sequence and their qualities.Chapter3is concerned with the existence of almost periodic solution, asymp-totically almost periodic solution and pseudo almost periodic solution for nonlinear difference equation with delay:...
