This text is an essentially self-contained treatment of material that is normally<br/>found in a first year graduate course in real analysis. Although the presentation is<br/>based on a modern treatment of measure and integration, it has not lost sight of<br/>the fact that the theory of functions of one real variable is the core of the subject.<br/>It is assumed that the student has had a solid course in Advanced Calculus and has<br/>been exposed to rigorous ",  arguments. Although the book’s primary purpose is<br/>to serve as a graduate text, we hope that it will also serve as useful reference for<br/>the more experienced mathematician.<br/><br/>
