Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In theoretical physics and mathematics, the Wess-Zumino-Witten (WZW) model, also called the Wess-Zumino-Novikov-Witten model, is a simple model of conformal field theory whose solutions are realized by affine Kac-Moody algebras. It is named after Julius Wess, Bruno Zumino, Sergei P. Novikov and Edward Witten. Let G denote a compact simply-connected Lie group and g its simple Lie algebra. Suppose that ¿ is a G-valued field on the complex plane. More precisely, we want ¿ to be defined on the Riemann sphere S2, which is the complex plane compactified by adding a point at infinity.
