| Abstract: | In this paper, the ralation between two different twist map definitions is discussed . Then using Mather twist map theorem and Poincare-Birkhoff fixed points theorem, the existence of periodic solutions and almost periodic solutions of the differential equtions is studied throuth Poincare map of the differential systems. |
