Deux Résultats autour du Théorème de Restriction de Chevalley
Journal of Lie theory, Tome 17 (2007) no. 3, pp. 583-59
We use Dunkl's operators to give an elementary proof of the surjectivity in the Chevalley's restriction theorem. In the second part of this article we describe the image of the invariants by the restriction map in the case of Takiff algebras, there are some similarities with super Lie algebras. We extend this result to Takiff symmetric space.
