MATH4061: Metric Spaces
2024 unit information
Topology, developed at the end of the 19th Century to investigate the subtle interaction of analysis and geometry, is now one of the basic disciplines of mathematics. A working knowledge of the language and concepts of topology is essential in fields as diverse as algebraic number theory and non-linear analysis. This unit develops the basic ideas of topology using the example of metric spaces to illustrate and motivate the general theory. Topics covered include: Metric spaces, convergence, completeness and the Contraction Mapping Theorem; Metric topology, open and closed subsets; Topological spaces, subspaces, product spaces; Continuous mappings and homeomorphisms; Compactness Connectedness Hausdorff spaces and normal spaces. You will learn methods and techniques of proving basic theorems in point-set topology and apply them to other areas of mathematics including basic Hilbert space theory and abstract Fourier series. By doing this unit you will develop solid foundations in the more formal aspects of topology, including knowledge of abstract concepts and how to apply them. Applications include the use of the Contraction Mapping Theorem to solve integral and differential equations.

At the completion of this unit, you should be able to:
- LO1. Explain and apply the foundational ideas of point set topology
- LO2. Construct metric topologies, define open/closed sets of the metric spaces, and identify and explain the relationships between these and continuity and other properties of the metric space.
- LO3. Find and rigorously prove properties of several important classes of sequences in metric spaces
- LO4. Synthesise knowledge from fundamental theorems of topological spaces and continuous mappings and use this to prove new results
- LO5. Demonstrate a broad and deep understanding of important concepts in topology and exercise critical thinking to identify and use these concepts to analyse examples and create novel conclusions
- LO6. Solve problems about differential equations using the contraction mapping theorem
- LO7. Apply the concepts of separable spaces and separation properties in both simple and complex examples.
- LO8. Write proofs and transfer the theory of metric spaces to other areas of mathematics.
Unit availability
This section lists the session, attendance modes and locations the unit is available in. There is a unit outline for each of the unit availabilities, which gives you information about the unit including assessment details and a schedule of weekly activities.
The outline is published 2 weeks before the first day of teaching. You can look at previous outlines for a guide to the details of a unit.
