5.0 out of 5 stars A Perfect Introduction to Real Analysis., March 16, 2003

By	Samael (Chicago, IL USA) - See all my reviews

This is the best book ever written on introductory classical real analysis. Better than other well regarded "classics", but sadly out of print (shame on all math instructors!). As the title implies, there is no abtract measure or integration theory, nor any functional analysis, but many theorems are stated in the context of general metric or even topological spaces. All the usual topics (for this level) are covered: Sequences and Series, Limits and Continuity, Differentiation, Elementary Functions and Integration. Lebesgue's measure is introduced in Chapter 2 and used in every chapter afterwards. The last chapter is the real treat: a wonderful introduction to Trigonometric Series. In the words of the author, this chapter is "a dessert that rewards the reader's hard labor expended in learning the fundamental principles of analysis".

Contrary to what another reviewer states, the book discusses R^n explicitily in the last 50 pages of the chapter on Integration (topics include integration on R^n, iteration of integrals, differential calculus in higher dimensions and transformation of integrals in R^n). And of course, R^n is also included implicitly in any theorem that's stated in terms of metric/topological spaces.

Probably the only shortcoming that anyone could find in this book is one that was also mentioned in another review: the lack of figures. Personally I like it that way, but that is just a matter of preferences, and in any case the author had a very good reason for not including any graphs/figures in his book: He is blind.

I can't end this review without including some excerpts from the author's preface (since Amazon doesn't have it):

"The subject is ... 'real analysis' in the sense that none of the Cauchy theory of analytic functions is discussed. Complex number, however, do appear throughout. Infinite series and products are discussed in the setting of complex numbers. The elementary functions are defined as functions of a complex variable. I do depart from the classical theme in Chapter 3, where limits and continuity are presented in the contexts of abstract topological and metric spaces."

"I have scrupulously avoided any presumption at all that the reader has any knowledge of mathematical concepts until they are formally presented here...for example, the number pi is not mentioned until is has been precisely defined in Chapter 5."

"One significant way in which this book differs from other texts at this level is that the integral we first mention is the Lebesgue integral on the real line."

"I sincerely hope that the exercise sets will prove to be a particularly attractive feature of this book. I spent at least three times as much effort in preparing them as I did on the main text itself...A great many of the exercises are projects of many parts which, when completed in the order given, lead the student by easy stages to important and interesting results."

5.0 out of 5 stars Outstanding, March 2, 2003

By A Customer

This review is from: Introduction To Classical Real Analysis (Hardcover)

The proofs are detailed, and there are plenty of important theorems that are worked-out. (Don't most of us pay less attention if a theorem is an exercise or worse skip them altogeter?)

So far as I can tell, this book does not discuss R^n, but it does introduce Lebegue integral in a concrete manner. (thank you!)
If you read about Cantor sets from Rudin only, you are missing out. Read about the Cantor sets in this book!
My only complain is not enough graphs and illustrations, but this book is better than the baby Rudin (Principles of Analysis).

5.0 out of 5 stars Not for the faint of heart, but rewarding for the determined, June 19, 2008

By	Daniel J. Grubb (Sycamore, Illinois, USA) - See all my reviews (REAL NAME)

I am one of Karl's PhD students.

It is a sad, almost criminal, fact that this wonderful book is out of print. It provides a rigorous and accurate presentation of elementary real analysis using the Lebesgue integral. No, there are not diagrams, but this book is for those who want proofs, not just warm fuzzy hand-waving. The standard theory is stated accurately and proven in detail in the main part of the book, but the true strength of this book is in the exercises. There, step-by-step, an incredible range of good examples and mind-bending theorems are presented. Do you want an example of a differentiable function with bounded derivative that is monotone on no interval? It's there. Do you want a proof that *most* differentiable functions are like this (in a well-defined sense)? It's there.

The primary failure of this book, though, is its index. Karl knew exactly how he wanted to describe each result, but almost nobody else knows his system. It would be a real service to the mathematical community to re-write the index and get this book into the Dover series or at least into print again.
