Abstract
In this note we realise current algebra with anomalous terms in terms of a U(1) gauge theory, in the space of maps M from S1 into a compact Lie group corresponding to the current algebra. The Wilson loop around a closed curve in M is shown to be the Wess–Zumino–Witten term. This discussion enables a simple understanding of the non-Abelian anomaly in the Schrödinger picture.
