Abstract
Letn be an integer. Denote byAn one of the following two graded vector spaces: (a) the space of all multilinear Poisson polynomials of degreen (with a grading described below), or (b) the cohomology of the space of alln-uples of complex numbersz1,..., zn withzi≠zj fori≠j. We prove that the natural action of Σ n on each homogeneous component ofAn can be extented to an “hidden” Σ n+1 -action and we compute the corresponding character (the Σ n -character being already given by Klyaschko and Lehrer-Solomon formulas).
