Abstract : Generalization of the Diliberto theory of periodic surfaces to the case of singular perturbation has been made. In this paper two basic types of singularly perturbed systems of ordinary differential equations have been investigated and the existence, continuous dependence on parameter and uniqueness of periodic surfaces have been obtained.
