High Energy Physics - Theory 2016-09-06 v1

Abstract

The abelian sigma model in (1+1) dimensions is a field theoretical model which has a field ϕ:S1S1 \phi : S^1 \to S^1 . An algebra of the quantum field is defined respecting the topological aspect of the model. It is shown that the zero-mode has an infinite number of inequivalent quantizations. It is also shown that when a central extension is introduced into the algebra, the winding operator and the momenta operators satisfy anomalous commutators.
