Entry requirements

MM549 og MM845 or similar courses.

Academic preconditions

Students taking the course are expected to:

  • Have a basic knowledge of topology and functional analysis, corresponding the contents of the courses MM549 and MM845.
  • Be able to use basic arguments from topology.
  • Be able to work independently with linear algebra.
  • Have a basic knowledge of the theory of groups and rings.

Course introduction

The aim of the course is to introduce the student to the basics of the
theory of operator algebras, with emphasis on the theory of C*-algebras
and operators on Hilbert spaces. The material covered is important in
almost all aspects of modern analysis. The course builds on the
knowledge acquired in the courses MM549 (Topology and complex analysis) and MM845 (Functional analysis) and gives the student the necessary
prerequisites to specialize in operator algebra theory during their
master’s studies.

In relation to the competence profile of the degree it is the explicit focus of the course to:

  • Give the competence to take responsibility for the academic development and specialization.
  • Give the competence to develop an overview of the interplay between different mathematical disciplines.
  • Give skills to work concretely with Hilbert spaces and their operators.
  • Give skills to use central functional analytic tools (the Hahn Banach theorem and its consequences)
  • Give knowledge and understanding of concrete examples of operator algebras.
  • Give knowledge of the theory of commutative C*-algebras.
  • Give knowledge of the theory of operators on Hilbert spaces.

Expected learning outcome

The learning objectives of the course are that the student demonstrates the ability to:

  • Reproduce definitions and results, including their proofs, covered in the course.
  • Be able to use these results to analyse concrete examples.
  • Formulate and present definitions, proofs and calculations in a mathematically rigorous way.


The following main topics are contained in the course:

  • The Gelfand transform
  • Representation theory for C*-algebras
  • The Gelfand Naimark theorem
  • The spectral theorem for selfadjoint operators
