From the reviews:
This book finally appears in the mother-tongue of the authors after an odyssey of some 20 years. Each chapter consists of several sections, at the end of each of which is a good set of exercises. There are indeed more references to the historical development of the subject, and historical examples, than one finds in the traditional analysis text. The text should serve students and faculty at German-speaking universities very well . (Gerald A. Heuer, Zentralblatt MATH, Vol. 1247, 2012)
