Course content

The course gives an introduction to C*-algebras and von Neumann algebras, which are the most important classes of operator algebras. Such algebras have fundamental applications in various areas of mathematics and in quantum physics. After having covered the basic results in the theory, some important classes of examples will be studied. The choice of examples may vary from one year to another, depending on the interests of the students following the course.

Learning outcome

After completing the course you:

  • are familiar with the definitions of C*-algebras and von Neumann algebras, and with basic related concepts, such as *-homomorphisms, ideals, quotients, approximate units and multiplier algebras;
  • know about the positive cone of a C*-algebra, how it induces an order on the self-adjoint elements and how it is used to define states;
  • know how to construct the GNS-representation associated with a state and how to represent a C*-algebra faithfully as bounded operators on a Hilbert space;
  • know the connection between pure states and irreducible representations of a C*-algebra;
  • have a good understanding of several operator topologies and know how to characterize von Neumann algebras with the help of double commutants;
  • can describe C*-algebras of compact operators and have a knowledge of other important classes of C*-algebras.

Admission

Students admitted at UiO must apply for courses in Studentweb. Students enrolled in other Master's Degree Programmes can, on application, be admitted to the course if this is cleared by their own study programme.

Nordic citizens and applicants residing in the Nordic countries may apply to take this course as a single course student.

If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures for international applicants.

Prerequisites

Recommended previous knowledge

MAT4450 - Advanced Functional Analysis.

Explanations and appeals

Resit an examination

Students who can document a valid reason for absence from the regular examination are offered a postponed examination at the beginning of the next semester.

Re-scheduled examinations are not offered to students who withdraw during, or did not pass the original examination.

Withdrawal from an examination

It is possible to take the exam up to 3 times. If you withdraw from the exam after the deadline or during the exam, this will be counted as an examination attempt.

Special examination arrangements

Application form, deadline and requirements for special examination arrangements.

Evaluation

The course is subject to continuous evaluation. At regular intervals we also ask students to participate in a more comprehensive evaluation.
