Dimension des fibres de Springer affines pour les groupes

Published 5 Mar 2012 in math.AG, math.GR, and math.RT | (1203.0975v3)

Abstract: Following Steinberg, we construct an adjoint quotient for the Vinberg semi-group and a section to this quotient. Then, after Ng^o, we show the existence of a regular centralizer on it and use it to compute the affine Springer fibers for groups.
