Firstly, we propose a concept of uniformly almost periodic functions on almost periodic time scales and investigate some basic properties of them. When time scale or , our definition of the uniformly… Expand

We first propose the concept of almost periodic time scales and then
give the definition of almost periodic functions on almost periodic time scales, then by
using the theory of calculus on time… Expand

Abstract By using the continuation theorem of coincidence degree theory, sufficient and realistic conditions are obtained for the existence of positive periodic solutions for both periodic… Expand

The existence and the global attractivity of a positive periodic solution of the delay differential equationy(t)=y(t) F[t, y](t-τ1(t)),⋯,y(t−τn(t))] are studied by using some techniques of the Mawhin… Expand
