A computation of the Kontsevich integral of torus knots. (English) Zbl 1082.57009

In this paper, the author studies the Kontsevich integral of torus knots. The author constructs a series of diagrams made of circles joined together in tree-like fashion and colored by some special rational functions. It is shown that this series codes exactly the unwheeled rational Kontsevich integral of torus knots and that it behaves simply under branched coverings. The Kontsevich integral is very difficult to compute and up to the present only the precise expression of the Kontsevich integral for the unknot was conjectured and proven in two papers [D. Bar-Natan, S. Garoufalidis, L. Rozansky and D. P. Thurston, Isr. J. Math. 119, 217–237 (2000; Zbl 0964.57010) and D. Bar-Natan, T. Q. Le Thang and D. P. Thurston, Geom. Topol. 7, 1–31 (2003; Zbl 1032.57008)]. Here the author gives a complete formula for a family of nontrivial knots extending the authors own work in [J. Marché, Topology Appl. 143, No. 1–3, 15–26 (2004; Zbl 1055.57013)].
