Learning outcomes

In order to pass the course (grade 3) the student should be able to

• give an account of important concepts and definitions in the theory of linear spaces over arbitrary fields;
• exemplify and interpret important concepts in specific cases;
• formulate important results and theorems covered by the course;
• describe the main features of the proofs of important theorems;
• use the theory, methods and techniques of the course to solve mathematical problems;
• present mathematical arguments to others.

Content

Linear spaces over arbitrary fields, sums and direct sums of subspaces, the dimension theorem, quotient spaces. tensor product. Linear transformations. Linear functionals, the dual space, dual bases. The canonical isomorphism between a linear space of finite dimension and its bidual. Forms: bilinear, Hermitian, symmetric, alternating, quadratic. Inner product spaces (complex and real): orthogonal projection, the method of least squares. Linear operators: Hermitian, symmetric, unitary, orthogonal, normal, the spectral theorem , simultaneous diagonalisation, eigenspaces and generalised eigenspaces, the characteristic polynomial and the minimal polynomial, Jordan's normal form over complex numbers.
