A concise yet elementary introduction to measure and integration theory, which are vital in many areas of mathematics, including analysis, probability, mathematical physics and finance. In this highly successful textbook the core ideas of measure and integration are explored, and martingales are used to develop the theory further. Additional topics are also covered such as: Jacobi's transformation theorem; the RadonNikodym theorem; differentiation of measures and HardyLittlewood maximal functions.
In this second edition, readers will find newly added chapters on Hausdorff measures, Fourier analysis, vague convergence, and classical proofs of the RadonNikodym and Riesz representation theorems. All proofs are carefully worked out with utmost clarity to ensure full understanding of the material and its background.
Requiring few prerequisites, this book is a suitable text for undergraduate lecture courses or self-study. Numerous illustrations and over 400 exercises help to consolidate and broaden the reader's knowledge. Full solutions to all exercises are available on the author's webpage at www.motapa.de.

List of Symbols
This is intended to aid cross-referencing, so notation that is specific to a single section is generally not listed. Some symbols are used locally, without ambiguity, in senses other than those given below. Numbers following entries are page numbers, with the occasional (Pr m.n ) referring to Problem m.n on the respective page.
Unless stated otherwise, binary operations between functions such as fg , fg , fg , fg , comparisons fg , f or limiting relations fnnf , limnfn , liminfnfn , limsupfn , supifi or infifi are always understood pointwise.
Alternatives are indicated by square brackets, i.e., if A [ B ] then P [ Q ] should be read as if A then P and if B then Q .
