| Description:
| Aims: To deepen understanding of linear algebra, provide a solid introduction to inner product spaces, and introduce multilinear algebra, with emphasis on bilinear forms. Learning Outcomes: After taking this unit, students should be able to: * Demonstrate understanding of vector spaces and abstract linear algebra, including dual spaces and bilinear forms. * State and prove basic results about inner product spaces and linear operators on such spaces. * Diagonalise symmetric and hermitian matrices. * Classify quadratic forms in theory and practice. Skills: Numeracy T/F A Problem Solving T/F A Written and Spoken Communication F (in tutorials) Content: Vector subspaces, sums and intersections, complementary subspaces, quotients. Dual spaces and bases, transpose of a linear map, annihilators. Inner product spaces over R and C. Cauchy-Schwarz inequality and applications. Gram-Schmidt orthonormalization. Orthogonal subspaces and complements. Duality. Linear operators on inner product spaces. Orthogonal and unitary groups; (skew) symmetric and (skew) hermitian matrices.
