### Learning Outcomes

On successful completion of this module students should be able to:

Demonstrate knowledge of examples of topologies.

Demonstrate an ability to construct new topological spaces from old.

### Brief description

Commonly known as 'rubber-sheet geometry', Topology is a subject, which has arisen essentially from abstracting certain characteristics of space, provides an extremely general framework that is used in many areas of science, including mathematics, physics and computer science. This module develops ideas found in earlier mathematical modules on analysis to provide a rigorous and, in a sense, elegantly simple set of concepts that will be extremely useful to those pursuing a career in science.

### Content

Topological properties of subsets in n-dimensional Euclidean space: open sets; topological equivalence of sets; convergence; continuity; development of topological axioms (generalisation to metric spaces).
Topological spaces: definition of a topological space; bases; relative topology; product topology.
Elementary topological properties: closed sets; interior points; closure; isolated points; boundary; Hausdorff separation axiom.
Continuity: definition of continuity; open maps; homeomorphisms; simple topological invariants.
Compactness: definition of compactness; compact sets in n-dimensional Euclidean space.
Connectivity: connected and disconnected spaces; path connected spaces; Jordan curve theorem.
Identification spaces: examples include circle; torus; Mobiüs band; Klein bottle.

### Aims

To develop certain notions of space that students will have already been exposed to in a much more general and abstract framework that can be applied to many areas of science.
