Abstract

The Drinfeld-Sokolov reduction method has been used to associate with glngl_n extensions of the matrix r-KdV system. Reductions of these systems to the fixed point sets of involutive Poisson maps, implementing reduction of glngl_n to classical Lie algebras of type B,C,DB, C, D, are here presented. Modifications corresponding, in the first place to factorisation of the Lax operator, and then to Wakimoto realisations of the current algebra components of the factorisation, are also described.
