Learning Outcomes
Subject-specific Knowledge:
- By the end of the module students will: be able to solve novel and/or complex problems in Number Theory.
- have a systematic and coherent understanding of theoretical mathematics in the field of Number Theory.
- have acquired a coherent body of knowledge of these subjects demonstrated through one or more of the following topic areas:
- Euclidean rings, principal ideal domains, uniqueness of factorization.
- Algebraic number fields (especially Quadratic fields).
- Applications to Diophantine equations.
- Student will also have a knowledge and understanding of a topic related to the areas listed under content.
Subject-specific Skills:
- In addition students will have specialised mathematical skills in the following areas which can be used with minimal guidance: Abstract reasoning.
- Students will have an ability to read independently to acquire knowledge and understanding in related areas.
Key Skills:
Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module
- Lectures demonstrate what is required to be learned and the application of the theory to practical examples.
- Subject material assigned for independent study develops the ability to acquire knowledge and understanding in related areas.
- Assignments for self-study develop problem-solving skills and enable students to test and develop their knowledge and understanding.
- 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.
- The end-of-year examination assesses the knowledge acquired and the ability to solve predictable and unpredictable problems.
