### Maximum principle and existence of almost-periodic solutions of second-order differential systems

Philippe Cieutat

#### Abstract

We give sufficient conditions for the existence of almost-periodic solutions of the second-order differential system $u'' = f(t,u,u')$, which satisfies the maximum principle. Our hypotheses do not impose the uniqueness of bounded solutions.
