Perturbation methods have always been an important tool for treating nonlinear differential equations. Now the drudgery associated with them has been eliminated

This book gives a thorough introduction to both regular and singular perturbation methods for algebraic and differential equations.

First published in 1994. Routledge is an imprint of Taylor & Francis, an informa company.

This book is a revised and updated version, including a substantial portion of new material, of our text Perturbation Methods in Applied Mathematics (Springer V

This book develops methods for describing random dynamical systems, and it illustrats how the methods can be used in a variety of applications. Appeals to resea
