The coefficients of the HOMFLYPT and the Kauffman polynomials are   pointwise limits of Vassiliev invariants
  The Vassiliev conjecture states that the Vassiliev invariants are dense in the space of all numerical link invariants in the sense that any link invariant is a pointwise limit of Vassiliev invariants.   In this article, we prove that the Vassiliev conjecture holds in the case of the coefficients of the HOMFLY and the Kauffman polynomials.
