摘要
To a finite type knot invariant, a weight system can be associated, which is a function on chord diagrams satisfying so-called 4-term relations. In particular, a weight system can be associated to any metrized Lie algebra. We extend these Lie algebra weight systems to permutations and provide an recursion for its computation.
