A boudary value problem is studied for a system of nonlinear differential difference equations of retarded types. We investigate an existence theorem of solutions, a method of approximation and an error estimation and can prove two main theorems. The first theorem says that one can assure the existe

In this paper, we present a method for approximating the solution of initial value ordinary differential equations with a priori error bounds. The method is based on a Chebyshev perturbation of the original differential equation together with the Frobenius method for solving the equation. Chebyshev
