| Abstract: | The almost periodic solutions for a class of fourth order nonlinear dynamical systems are studied by using the Lerag-Schauder fixed point theorem and the method of Liapunov functions. We obtain the sufficient conditions which guarantee the existence of the almost periodic solutions of the dynamical systems. |

| Keywords: | almost periodic solution existence Liapunov function |
