On successful completion of this module students should be able to:
1. Demonstrate knowledge of examples of sigma-algebras and measures;
2. Determine the Lebesgue measure of certain Borel sets;
3. Determine whether a function is measurable;
4. Determine whether a function is integrable;
5. Demonstrate that the Riemann and Lebesgue integrals co-incide for a class of functions;
6. Apply convergence theorems to justify the exchange of limiting processes for integrals;
7. Demonstrate knowledge of Lebesgue measure and its properties.
This course is a rigourous practical guide to the basic technical foundations and main principles which underpin the classical notions of area, volume, and the related idea of an integral. After reviewing the Riemann integral, its properties and limitations, the beautiful and poweful theory due to Lebesgue is introduced. The emphasis is on examples and applications of the main theorems rather than proofs of the classical results.
