Query: Chromatic weight systems and the corresponding knot invariants   This paper contains a proof that chromatic weight systems, introduced by
Chmutov, Duzhin and Lando, can be expressed in terms of weight systems
associated with direct sums of the Lie algebras gl_n and so_n. As a consequence
the Vassiliev invariants of knots corresponding to the chromatic weight systems
distinguish exactly the same knots as a one variable specialisation Y of the
Homfly and Kauffman polynomial.
