Lebesgue's theory of integration
NettetThe book is short and very readable, and it introduces Lebesgue integration on the real line in a very understandable way. In general, I think that it is much better to introduce measure theory and Lebesgue integration in the specific context of the real line and $\mathbb{R}^n$, perhaps moving on to general measure spaces after this is done.

NettetThe definition of a Lebesgue-Stieltjes integral now follows from the general definition of a Lebesgue integral. Definition A. 1.3. Let / — : R be a Borel measurable function, G : R-* R a right-continuous increasing function, and μ the Borel measure corresponding to G. For any Borel set B C R, defin B fdGe t / o b fle /rf/i / . Nettettheory to understand measurable functions and give a foundation for integration theory. Next, we develop the Lebesgue integral with the goal of understanding the dominated convergence theorem, which can be thought of as the result of introductory Lebesgue integration. Finally, we will explore one of the most important applications of Lebesgue

Surprisingly, Henstock (in 1955) and Kurzweil (in 1957) came up with a new version of the Riemann integral-call it the HK-integral (see [71)-that is "as good as" the Lebesgue … NettetThe Lebesgue integral This part of the course, on Lebesgue integration, has evolved the most. Initially I followed the book of Debnaith and Mikusinski, completing the space of step functions on the line under the L1 norm. Since the ‘Spring’ semester of 2011, I have decided to circumvent the discussion of step functions, proceeding directly by
