- Rank + nullity = dimension, matrix representation, change of basis, canonical form, determinant.
- Vector space of linear maps, dual space, dual basis.
- Eigenvalues and Eigenspaces: Characteristic polynomial, similar matrices, diagonalisation, Cayley Hamilton theorem, symmetric, skew-symmetric matrices, sesquilinear forms, Hermitian and unitary matrices.
- Sturm-Liouville theory: Special functions as solutions of S-L equation, eigenvalues and eigenfunctions and applications.
- Normal Forms: Endomorphisms.
- Invariant subspaces, minimum polynomial, rational normal form.
- Jordan normal form.

#### Learning Outcomes

Subject-specific Knowledge:

- By the end of the module students will: be able to solve a range of predictable and unpredictable problems in Linear Algebra.
- have a knowledge and understanding of fundamentals of Linear Algebra.
- have a knowledge and understanding of fundamental theories of these subjects demonstrated through one or more of the following topic areas: Vector Spaces.
- Linear Mappings.
- Eigenvalues and Eigenspaces.
- Inner Product Spaces.
- Sturm-Liouville Theory.
- Normal Forms.

Subject-specific Skills:

- In addition students will have the ability to undertake and defend the use of alternative mathematical skills in the following areas with minimal guidance: Abstract reasoning and spatial awareness

Key Skills:

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

- Lecturing demonstrates what is required to be learned and the application of the theory to practical examples.
- Weekly homework problems provide formative assessment to guide students in the correct development of their knowledge and skills.
- Tutorials provide active engagement and feedback to the learning process.
- The end-of-year examination assesses the knowledge acquired and the ability to solve predictable and unpredictable problems.
