It is a wonderful book that distinguishes itself by the clarity of presentation, by the fact that it is self-contained and has many exercises at various degrees of difficulty (among many other great qualities.)...It is a very elegant and complete treatment of topics usually not found in analysis books...The exercises are plenty and very well selected. In summary, we have here a very-very good, self-contained, well written book, including many applications and exercises, that can be used as a text for courses, as self-study, and/or as a basis for research in mathematics or even other disciplines. This book is a wonderful read.
