Measure and integral

the long version

"This book is a systematic exposition of the theory of measure and integration. It is intended for students, and also as a reference work. The body of the text can be read by a student with a firm background in analysis, whereas the supplements treat more advanced topics, and require somewhat more maturity. Although the results given here are the standard ones, the authors have taken a new approach, systematically exploiting the concepts of -ring and -simplicity."--Publisher's Description.
