Lax representation of WZNW-like systems
2006, vol. 11, no. 4, pp. 435-453
In this paper, we establish new integrable systems which are similar to WZNW (Wess–Zumino–Novikov–Witten) systems and non-abelian affine Toda models. One of these systems is a new integrable extension of the well known sine-Gordon equation.
