Module description

The module continues the study of abstract algebra by further developing the theory of groups. The theory will be illustrated through examples in settings that students will already have encountered.

Module aims

The module aims:
To continue the study of groups and to teach how an extensive and important theory can be developed by logical deductions from a small number of axioms.

Module learning outcomes

On completion of the course, students should:
1. have a systemic understanding of key definitions in the theory of groups and critical awareness of how they interact and support each other
2. select and apply relevant theorems to examples
3. construct arguments to prove properties of groups
4. solve problems involving homomorphisms between pairs of groups
5. formulate counterexamples to statements
6. understand the concept of a group presentation
7. recognise and work with cyclic, dihedral, Fibonacci, and triangle groups,
8. deploy methods learned to distinguish pairs of groups defined by presentations or to prove they are isomorphic
9. apply geometric techniques to obtain and illustrate algebraic properties of particular groups

Disclaimer: The University makes every effort to ensure that this information on its Module Directory is accurate and up-to-date. Exceptionally it can be necessary to make changes, for example to programmes, modules, facilities or fees. Examples of such reasons might include a change of law or regulatory requirements, industrial action, lack of demand, departure of key personnel, change in government policy, or withdrawal/reduction of funding. Changes to modules may for example consist of variations to the content and method of delivery or assessment of modules and other services, to discontinue modules and other services and to merge or combine modules. The University will endeavour to keep such changes to a minimum, and will also keep students informed appropriately by updating our programme specifications and module directory.
