Gerbes, (twisted) K-theory, and the supersymmetric WZW model
Jouko Mickelsson
The aim of this talk is to explain how symmetry breaking in a quantum field theory problem leads to a study of projective bundles, Dixmier-Douady classes, and associated gerbes. A…

Trace extensions, determinant bundles, and gauge group cocycles
Joakim Arnlind, Jouko Mickelsson
We study the geometry of determinant line bundles associated to Dirac operators on compact odd dimensional manifolds. Physically, these arise as (local) vacuum line bundles in quan…
