    Lax Representation of Chiral-Type Systems
    2007, Vol. 3, No. 2, pp.  175-202
    The conditions which are necessary for chiral-type systems to admit the Lax representation with compact Lie algebras are obtained in this paper. We also establish new integrable systems which are similar to WZNW (Wess-Zumino-Novikov-Witten) systems and non-abelian affine Toda models. One of such a system is a new integrable extension of the well known sin-Gordon equation.
    Keywords: Lax representation, WZNW systems, symmetric spaces, Lie algebras, nonlinear sigma-models
