Designed for students in mathematics and physics who have already taken courses in real analysis, this textbook for measure theory and functional analysis explains fundamental concepts in clear and concrete terms. Franks (mathematics, Northwest U.) introduces Lebesgue integration by offering straightforward problems that demonstrate regulated and Riemann integrals, Lebesgue measures and integrals, the integral of unbounded functions, classical Fourier series and ergodic transformations. Appendices include the specific Lebesgue measures, the background and foundations for the sets and the outline for a non-measurable set. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)
