Module summary

This module will introduce measure theory and Lebesgue integration. It will develop powerful tools of the theory of Lebesgue integration and will demonstrate that the Lebesgue integral can be computed by familiar methods whenever they are applicable. Amongst various examples of measures it will construct Lebesgue measure which extends the familiar notions of length, areas and volume, and explore advanced topics such as the Radon-Nikodym derivative and Lebesgue’s density theorem.

Module learning outcomes

At the end of the module students should be able to:

  1. Use measure space and apply their properties in examples.

  2. Apply Caratheodory's criterion in the context of the construction and properties of Lebesgue measure and measurability of Borel sets

  3. Demonstrate knowledge of the construction of the Lebesgue integral and its key properties.

  4. Compute Lebesgue integrals using the Fundamental Theorem of Calculus, Monotone and Dominated Convergence Theorems, and the Tonelli and Fubini Theorems.

The information on this page is indicative of the module that is currently on offer. The University constantly explores ways to enhance and improve its degree programmes and therefore reserves the right to make variations to the content and method of delivery of modules, and to discontinue modules, if such action is reasonably considered to be necessary. In some instances it may be appropriate for the University to notify and consult with affected students about module changes in accordance with the University's policy on the Approval of Modifications to Existing Taught Programmes of Study.
