In this paper we investigate the existence and uniqueness of almost periodic and pseudo almost periodic solution for nonlinear differential equation with reflection of argument. For the case of almost periodic forced term , we consider the frequency modules of the solutions.
Keywords: almost periodic solution, pseudo almost periodic solutions differential equations, reflection of the argument, fixed point method
