Knot theory with the Lorentz group
We analyse perturbative expansions of the invariants defined from unitary representations of the Quantum Lorentz Group in two different ways, namely using the Kontsevich Integral and weight systems, and the R-matrix in the Quantum Lorentz Group defined by Buffenoir and Roche. The two formulations are proved to be equivalent; and they both yield ℂ[[h]]h-valued knot invariants related with the Melvin-Morton expansion of the Coloured Jones Polynomial.

La décomposition en poids des algèbres de Hopf
Si est une algèbre de Hopf commutative ou cocommutative et connexe, les puissances de convolution et le logarithme, au sens du produit de convolution, du morphisme identité de satisfont à diverses identités algébriques. L’algèbre de Hopf admet en particulier une décomposition en poids sous l’action des morphismes , dont nous étudions les propriétés.
