Sur les representations de Krammer generiques
Ivan Marin
We define a representation of the Artin groups of type ADE by monodromy of generalized KZ-systems which is shown to be isomorphic to the generalized Krammer representation original…
Caracteres de rigidite du groupe de Grothendieck-Teichmuller
Ivan Marin
Let $\k$ be a (topological) field of characteristic 0. Using a Drinfeld associator , a representation of the braid group over the field $\k((h))$ of Laurent series can be…
Monodromie algebrique des groupes d'Artin diedraux
Ivan Marin
Towards the study of the representation theory of any dihedral Artin group B, we build rational morphisms from B to the group of invertible elements of the associated infinitesimal…
L'algebre de Lie des transpositions
Ivan Marin
For any we obtain the decomposition in simple factors of the Lie subalgebra of the group algebra of the symmetric group on letters generated by the transpositions. T…
