ap-1189	Mickelsson, J.	From Gauge Anomalies to Gerbes and Gerbal Representations: Group Cocycles in Quantum Theory	2010	6	.pdf	application/pdf	4371	246	74	Then we investigate how group cohomology of degree 3 comes from a prolongation problem for group extensions and we discuss its role in quantum field theory. In Section 3 we then explain how 3-cocycles come from a prolongation problem for group extensions.	cache/ap-1189.pdf	txt/ap-1189.txt
