An asymptotic theory for nonlinear functional differential equations
The Hartman-Wintner theorem on asymptotic integration is established for a certain class of functional differential equations with nonlinear perturbations, by looking them as abstract ordinary differential equations. Results for delay differential equations are included in this study. Consequences and applications are also shown. (C) 2002 Elsevier Science Ltd. All rights reserved.
