Occurrence Teaching cycle
A Spring Term 2022-23

Module aims

  • To explore the exotic world of linear operators in infinitely many dimensions.

  • To compare linear operators in finitely many and infinitely many dimensions.

  • To encounter specific applications of the general theory.

Module learning outcomes

  • The definition and significance of bounded and compact operators.

  • The idea of the spectrum, and the difference between 'spectral point' and 'eigenvalue'.

  • The Spectral Theorem and functional calculus as a generalisation of the orthogonal diagonalisation theorem.


Module content



  • The algebra of bounded operators in a Hilbert space and the ideals of finite-rank, Hilbert-Schmidt and compact operators.

  • Definitions and properties of self-adjoint operators.

  • Spectral Theorem and functional calculus illustrated by compact normal operators or bounded self-adjoint operators.

  • Applications including differential or integral equations.

The information on this page is indicative of the module that is currently on offer. The University is constantly exploring ways to enhance and improve its degree programmes and therefore reserves the right to make variations to the content and method of delivery of modules, and to discontinue modules, if such action is reasonably considered to be necessary by the University. Where appropriate, the University will notify and consult with affected students in advance about any changes that are required in line with the University's policy on the Approval of Modifications to Existing Taught Programmes of Study.
