Abstract:
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.
Keywords:
Lax representation, WZNW systems, symmetric spaces, Lie algebras, nonlinear sigma-models.
