Query: Lax Representation of WZNW-Like Systems   The Lax representation and Backlund transformations for the systems similar
to WZNW (Wess-Zumino-Novicov-Witten) systems and non-abelian affine Toda models
are obtained in present paper. One of these systems is a new integrable
extension of well known sine-Gordon equation.
