Operator algebras
Operator algebras is a fast expanding area of mathematics with remarkable applications in differential geometry, dynamical systems, statistical mechanics and quantum field theory. It is at the center of new approaches to the Riemann hypothesis and the standard model, and it forms a foundation for quantum information theory.
About the group
The research of the group in operator algebras at the University of Oslo has focus on diverse applications in harmonic analysis, dynamical systems, numerical approximation of spectra, quantum information theory, wavelet theory and noncommutative geometry of quantum groups.

C*seminar
For the time being our seminar takes place irregularly. It can be organized as a working seminar among some of the members of the group, or it can be a guest lecture, which will be announced on our seminarwebpage.
