Module Overview |
|
|
|
Prerequisites/Co-requisites |
MS113 Linear Algebra, MS202 Introduction to Metric Spaces
|
|
|
Module Aims |
The objectives are to introduce the students to the concept of a Hilbert space, which generalises Euclidean space to infinite dimensions, to introduce analysis and operators in a Hilbert space, and to indicate the range of applications where such concepts are needed.
|
|
|
Learning Outcomes |
At the end of the module the student should have
- a firm understanding of the concept of a function space, the basics of Hilbert spaces, the basic properties of operators acting on these spaces, as well as the basics of unbounded operators on a Hilbert space.
- a grasp of the importance of the concept of function spaces in applications, particularly in the analysis of differential and integral equations.

Module Content |
The contents of the lectures will include:
· Metric and normed spaces, their definitions and basic examples, including Euclidean space, discrete metric, and the L1 and L2-norm.
· Open and closed sets, Cauchy and convergent sequences, completeness.
· Pointwise versus uniform convergence and uniform limits of continuous functions.
· Fixed points and the Contraction Mapping Theorem; applications to e.g. (
Newton
) iteration, the Implicit Function Theorem and existence of solutions of ODEs.
· Inner product spaces, their definition and basic examples. Cauchy-Schwarz inequality and parallelogram law.
· Orthogonal systems, Bessel’s inequality.
Fourier analysis and applications (such as the wave equation). |
