    "abstract": "The Drinfeld-Sokolov reduction method has been used to associate with $gl_n$\nextensions of the matrix r-KdV system. Reductions of these systems to the fixed\npoint sets of involutive Poisson maps, implementing reduction of $gl_n$ to\nclassical Lie algebras of type $B, C, D$, are here presented. Modifications\ncorresponding, in the first place to factorisation of the Lax operator, and\nthen to Wakimoto realisations of the current algebra components of the\nfactorisation, are also described.",
