For all readers interested in real analysis.

* Real Analysis, Fourth Edition, *covers the basic material that every reader should know in the classical theory of functions of a real variable, measure and integration theory, and some of the more important and elementary topics in general topology and normed linear space theory. This text assumes a general background in

*and familiarity with the fundamental concepts of analysis.*

**mathematics**Classical theory of functions, including the classical Banach spaces; General topology and the theory of general Banach spaces; Abstract treatment of measure and integration.
