Abstract

Lie algebra valued equations translating the integrability of a general two-dimensional Wess-Zumino-Witten model are given. We found a simple solution to these equations and identified a new integrable nonlinear sigma model. This is a two-parameter deformation of the Wess-Zumino-Witten model.
