MATH202 Linear Algebra

This paper is an introduction to the fundamental ideas and techniques of linear algebra and the application of these ideas to computer science and the sciences.

The principal aim of this paper is for students to develop a working knowledge of the central ideas of linear algebra: vector spaces, linear transformations, orthogonality, eigenvalues and eigenvectors, and the spectral theorem.

We will explore applications of these ideas in science, computer science and engineering.

Paper Structure

Main topics:

  • Vector spaces over the real and complex numbers (mainly finite-dimensional), vector subspaces
  • Linear combinations, linear independence and span, bases, dimension, extending bases of subspaces, sum of subspaces, direct sums
  • Linear transformations and their properties, kernel and range, rank-nullity theorem
  • Representation of linear transformations by matrices, coordinate vectors, composition of linear transformations corresponds to products of matrices
  • Diagonalisation, invariant subspaces, eigenvalues and eigenvectors
  • Inner products, orthogonality, orthogonal projections, Cauchy-Schwartz inequality, inner-product norm, orthonormal bases, Gram-Schmidt process, orthogonal complements, minimisation problems
  • The adjoint of a linear transformation, self-adjoint and normal transformations, the real and complex spectral theorems, the singular-value decomposition of a matrix
