A Modern Theory of Integration
Share this pageRobert G. Bartle
The theory of integration is one of the twin pillars on which analysis is
built. The first version of integration that students see is the Riemann
integral. Later, graduate students learn that the Lebesgue integral is
“better” because it removes some restrictions on the integrands and the domains
over which we integrate. However, there are still drawbacks to Lebesgue
integration, for instance, dealing with the Fundamental Theorem of Calculus, or
with “improper” integrals.
This book is an introduction to a relatively new theory of the integral (called
the “generalized Riemann integral” or the “Henstock-Kurzweil integral”) that
corrects the defects in the classical Riemann theory and both simplifies and
extends the Lebesgue theory of integration. Although this integral includes
that of Lebesgue, its definition is very close to the Riemann integral that is
familiar to students from calculus. One virtue of the new approach is that no
measure theory and virtually no topology is required. Indeed, the book includes
a study of measure theory as an application of the integral.
Part 1 fully develops the theory of the integral of functions defined on a
compact interval. This restriction on the domain is not necessary, but it is
the case of most interest and does not exhibit some of the technical problems
that can impede the reader's understanding. Part 2 shows how this theory
extends to functions defined on the whole real line. The theory of Lebesgue
measure from the integral is then developed, and the author makes a connection
with some of the traditional approaches to the Lebesgue integral. Thus, readers
are given full exposure to the main classical results.
The text is suitable for a first-year graduate course, although
much of it can be readily mastered by advanced undergraduate
students. Included are many examples and a very rich collection of
exercises. There are partial solutions to approximately one-third of
the exercises. A complete solutions manual is available
separately.
Readership
Advanced undergraduates, graduate students and research mathematicians, physicists, and electrical engineers interested in real functions.
Reviews & Endorsements
The book presents its subject in a pleasing, didactically surprising, and well worth reading exposition. The proofs are, as a rule, easily understandable and the significance of the theorems that are worked through is illustrated by means of numerous examples. It can be recommended as a self-study book to every student with a basic foundation in analysis. It is also very suitable as a supplementary text for a course on integration on \(\mathbf{R}\).
-- Translated fromJahresbericht der Deutschen Mathematiker-Vereinigung
A comprehensive, beautifully written exposition of the Henstock-Kurzweil (gauge, Riemann complete) integral … There is an abundant supply of exercises which serve to make this book an excellent choice for a text for a course which would contain an elementary introduction to modern integration theory.
