Diagram formulas of the Viro-Polyak type for finit degree invariants
arXiv:math/9905162
Abstract
Vassiliev's knot invariants can be computed in different ways but many of them as Kontsevich integral are very difficult. We consider more visual diagram formulas of the type Polyak-Viro and give new diagram formula for the two basic Vassiliev invariant of degree 4.
