Operatoralgebraer (Operator algebras)

Operator algebras is a central area of mathematics with applications to several other mathematical disciplines and mathematical physics. The project aims at doing further research and education within operator algebras and closely related fields by a grou p consisting of Erik Alfsen, Erik Bedos, Ola Bratteli and Erling Størmer at the University of Oslo, Lars Tuset at Oslo University College and Trond Digernes, Magnus Landstad and Christian Skau at NTNU, in addition to their students. In addition will the p ostdocs Sergei Neshveyev (university postdoc in Oslo since Aug. 2003), Nadia S. Larsen (university postdoc in Oslo) and Toke Meier Carlsen (EU - postdoc in Trondheim 01.07.04 - 30.09.05 be members of the group. The research group is international and the members of the group have strong expertise in a diversity of areas, as described below : Erik Alfsen (Geometry of state spaces of operator algebras). Erik Bedos (Discrete magnetic Laplacians, amenability aspects for quantum groups, projective unitary representations and twisted Fourier analysis of discrete groups). Ola Bratteli (Wavelets and operator theory, noncommutative dynamical systems). Toke Meier Carlsen (C*-algebras associated to shift spaces). Trond Digernes (p-adic quantum systems). Magn us Landstad, (Hecke algebra and groupoid actions on C*-algebras). Nadia S. Larsen (Hecke algebras and C*-completions, crossed products of C*-algebras by semigroups of endomorphisms). Sergey Neshveyev (Noncommutative ergodic theory, boundary theory of qu antum discrete groups, noncommutative differential calculus, rigidity properties of group actions). Christian Skau (Induced equivalence relations of discrete group actions on Cantor sets, K-theoretic data defined by dynamics). Erling Størmer (Contraction s on von Neumann algebras, noncommutative information theory and entropy) Lars Tuset (Cyclic cohomology for Hopf algebras, tensor categories, Martin boundary for compact quantum groups).
