This book will be of interest for everybody working on perturbation theory indifferential equations. The book requires only a standard mathematicalbackground for engineers and does not require reference to the specialliterature. Topics which are covered include matrix perturbation theorysystems of ordinary differential equations with small parameter reconstructionand equations in partial derivatives. Boundary problems are not discussed inthis volume. The reader will find many examples throughout the book. «
