Group - Kontsevich invariant

In the mathematical theory of knots, the Kontsevich invariant, also known as the Kontsevich integral of an oriented framed link is the universal finite type invariant in the sense that any coefficient of the Kontsevich invariant is a finite type invariant, and any finite type invariant can be presented as a linear combination of such coefficients. It is also a universal quantum invariant in the sense that any quantum invariant may be recovered by substituting the appropriate weight system into any Jacobi diagram.
