Abstract : In this thesis, we presented a study to the behavior of some differential equations. In the first chapter, we presented some definitions and theorems that we need in this study. In the second chapter, by constructing an appropriate Lyapunov functional, we gave sufficient conditions of the uniform stability for non-linear fourth-order vector differential equation with variable delay. In the third chapter , we gave results on the uniform asymptotic stability, boundedness and square integrability of solutions of fourth-order differential equation with multiple delays. In the fourth chapter, we applied Mawhin’s continuous theorem to discuss the sufficient conditions for the existence and uniqueness of an w-periodic solution for a kind of third-order neutral functional differential equation.
