Module aims
This module aims to introduce Lebesgue's theory of measure and integration, which extends the familiar notions of volume and "area under a graph" associated with the Riemann integral. It will be demonstrated that the Lebesgue integral can be computed by familiar methods whenever they are applicable (anti-differentiation in dimension one, repeated one-dimensional integrals in higher dimensions), and that it is sufficiently wide in scope to give the powerful convergence theorems needed for more advanced applications.
Module learning outcomes
At the end of this module students should be able to:
-
Understand the construction and properties of Lebesgue measure, including the notion and properties of null set;
-
Understand the construction of the Lebesgue integral and know its key properties;
-
Compute Lebesgue integrals using the Fundamental Theorem of Calculus, Monotone and Dominated Convergence Theorems, and the Tonelli and Fubini Theorems.
