#### Prerequisites

- None

#### Corequisites

- Math Sciences II (MATH51760)

#### Excluded Combination of Modules

- None

#### Aims

- To acquire specialist knowledge in respect of several topics in Mathematical Sciences at MSc level, and to appreciate the highly rigorous and logical methods involved. In respect of the particular areas, to acquire ability in applying the theory and practice of this knowledge to standard and novel problems or in explaining fundamental aspects of the theory.

#### Content

- Students take three of the following units subject to the approval and with the advice of the course director. A balanced selection of at least twelve of these units will be offered each year, and a list of these will appear in the MSc booklet.
- Independent Study: Students choose under the guidance of the course director a topic for independent study. For each topic reading material appropriate to independent study at level 4 is specified and this will define the material to be studied.

#### Learning Outcomes

Subject-specific Knowledge:

- Students will, in each of the units studied, have an understanding of the specialised and complex mathematical theory together with mastery of a coherent body of knowledge.

Subject-specific Skills:

- Students will develop highly specialised and advanced mathematical skills in the areas studied. They will be able to solve complex, novel and specialised problems, draw conclusions and deploy abstract reasoning and mathematical intuition, with minimal guidance.They will develop their mathematical self-sufficiency and be able to read and understand advanced mathematics independently.

Key Skills:

- (1) Abstract reasoning, analytical thinking, problem solving, creativity and numeracy, written presentation of an argument.
- (2) The ability to learn actively and reflectively and to develop intuition, the ability to tackle material which is given both unfamiliar and complex.
- (3) Self-organisation, self-discipline and self-knowledge.

#### Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

- Lectures and assigned reading indicate what is required to be learned and the application of the theory to examples.
- Assignments for self-study develop problem-solving skills and enable students to test and develop their knowledge and understanding.
- Subject material assigned for independent study in several units develops the ability to acquire knowledge and understanding without dependence on lectures.
- Formatively assessed assignments provide practice in the application of logic and high level of rigour as well as feedback for the students and the lecturer on students' progress.
- Summative examinations assess the knowledge acquired and the ability to solve both standard and novel problems.
- The ability to solve problems will show that the key skills have been developed. (Group (1) is tested directly in the problem solving and group (2) either directly or indirectly by the testing of the knowledge acquired. For group (3), a student who has acquired the knowledge and skills to succeed in this module will necessarily have had to develop the ability to organise and execute a programme of work and will discover aspects of and limits to his/her ability.)
