Description
The core of the first edition of this book was devoted to what is commonly called "Caratheodory" measure theory, as contrasted with "Bourbaki" measure theory or "Daniell" integral theory. Without debating the relative merits of these various approaches to a modern theory of the integral, we see no point in changing our basic approach to the subject and, therefore, have made relatively few changes in the central portion of the book. Those who have used the first edition will certainly recognize the chapters on measure (general and specific), measurable functions, integrals, and derivatives. The beginning and the end have undergone some changes. Chapter 1 of the first edition was written in such a way as to make the book essentially self-contained. In 1953 this seemed realistic because, at that time, the chances were that some of this background material would have to be actively taught as part of a measure theory course. Since then there have appeared a number of adequate texts iJ?- undergraduate real analysis, so that today it seems appropriate to summarize this background material in capsule form-definitions and theorems, with proofs and exercises deleted. ; The major changes in the present edition come at the end. In the first edition we had a couple of sections designed to inform the student that there is such a thing as functional analysis. In the light of recent recommendations by the Committee on the Undergraduate Program in Mathematics; it now ·seems desirable to incorporate into the book a genuine introduction to this subject. Accordingly, we have added a new chapter giving the "big three" theorems (Hahn-Banach, Banach-Steinhaus, and closed-graph) together with a fairly thorough discussion of weak and weak* convergence in the standard function spaces.
