This monograph evolved from a set of lecture notes for a course entitled Real Analysis that
I taught at the University of California, Irvine. The subject of this course is the theory
of measure and integration. Its prerequisite is advanced calculus. All of the necessary
background material can be found, for example, in R. C. Buck's Advanced Calculus. The
course is primarily for beginning graduate students in mathematics but the audience usually
includes students from other disciplines too. The first five chapters of this book contain
enough material for a one-year course. The remaining two chapters take an academic
quarter to cover.
