From Gauge Anomalies to Gerbes and Gerbal Representations: Group Cocycles in Quantum Theory
In this paper I shall discuss the role of group cohomology in quantum mechanics and quantum field theory. First, I recall how cocycles of degree 1 and 2 appear naturally in the context of gauge anomalies. Then we investigate how group cohomology of degree 3 comes from a prolongation problem for grou...
