The paper contains a detailed exposition of the construction and properties of the Kontsevich integral invariant, crucial in the study of Vassiliev knot invariants. 

The Generating Functional of the Kontsevich Integral and its Derivation as a Holonomy

We introduce an algebra bundle of chord diagrams over the configuration space of N points in the complex plane on which we put the Knizhnik-Zamolodchikov connection. For that particular connection,

Knot invariants and configuration space integrals

After a short presentation of the theory of Vassiliev knot invariants, we shall introduce a universal finite type invariant for knots in the ambient space. This invariant is often called the

A Stringy Generalization of the Kontsevich Integral

We introduce a "minimal" Kontsevich integral that generates the original Kontsevich integral while at the same time producing ribbons whose boundaries are the braids on which the minimal Kontsevich

KONTSEVICH INTEGRAL FOR KNOTS AND VASSILIEV INVARIANTS

We review quantum field theory approach to the knot theory. Using holomorphic gauge, we obtain the Kontsevich integral. It is explained how to calculate Vassiliev invariants and coefficients in

On the Kontsevich integral of Brunnian links

The purpose of the paper is twofold. First, we give a short proof using the Kontsevich integral for the fact that the restriction of an invariant of degree 2n to (n+1)-component Brunnian links can be

Knot Theory With The Lorentz Group

We analyse the perturbative expansion of the knot invariants defined from the unitary representations of the Quantum Lorentz Group in two different ways, namely using the Kontsevich Integral and

On the Kontsevich integral for knotted trivalent graphs

We construct an extension of the Kontsevich integral of knots to knotted trivalent graphs, which commutes with orientation switches, edge deletions, edge unzips, and connected sums. In 1997 Murakami

On the Existence of Finite Type Link Homotopy Invariants

We show that for links with at most 5 components, the only finite type homotopy invariants are products of the linking numbers. In contrast, we show that for links with at least 9 components, there

On universal Vassiliev invariants

Using properties of ordered exponentials and the definition of the Drinfeld associator as a monodromy operator for the Knizhnik-Zamolodchikov equations, we prove that the analytic and the

AN UPPER BOUND FOR THE NUMBER OF VASSILIEV KNOT INVARIANTS

We prove that the number of independent Vassiliev knot invariants of order n is less than (n − 1)! — thus strengthening the a priori bound (2n − 1)!!

An almost-integral universal Vassiliev invariant of knots

A \total Chern class" invariant of knots is dened. This is a universal Vassiliev invariant which is integral \on the level of Lie algebras" but it is not expressible as an integer sum of diagrams.

The universal Vassiliev-Kontsevich invariant for framed oriented links

We give a generalization of the Reshetikhin-Turaev functor for tangles to get a combinatorial formula for the Kontsevich integral for framed oriented links. The rationality of the Kontsevich integral

SummaryA fundamental relationship is established between Jones' knot invariants and Vassiliev's knot invariants. Since Vassiliev's knot invariants have a firm grounding in classical topology, one
