Cellules de Calogero-Moser
Cédric Bonnafé, Raphaël Rouquier
Using the representation theory of Cherednik algebras at t=0 and a Galois covering of the Calogero-Moser space, we define the notions of left, right and two-sided Calogero-Moser ce…
Compactification des variétés de Deligne-Lusztig
Cédric Bonnafé, Raphaël Rouquier
We construct explicitly the normalisation of the Bott-Samelson-Demazure-Hansen compactification of Deligne-Lusztig varieties in their covering : we retrieve a result b…
Cohomologie des variétés de Deligne-Lusztig
François Digne, Jean Michel, Raphaël Rouquier
We study the cohomology of Deligne-Lusztig varieties with aim the construction of actions of Hecke algebras on such cohomologies, as predicted by the conjectures of Broué, Malle an…
Familles de caracteres de groupes de reflexions complexes
Gunter Malle, Raphael Rouquier
Nous etudions certains types de blocs d'algebres de Hecke associees aux groupes de reflexions complexes qui generalisent les familles de caracteres definies par Lusztig pour les gr…
Categories derivees et varietes de Deligne-Lusztig
Cedric Bonnafe, Raphael Rouquier
We prove a conjecture of Broue about the Jordan decomposition of blocks of finite reductive groups. We show that a block of a finite connected reductive group, in non-describing ch…
Quotients et extensions de groupes de reflexions complexes
David Bessis, Cedric Bonnafe, Raphael Rouquier
We give a geometric description of a certain class of epimorphisms between complex reflection groups. We classify these epimorphisms, which can be interpreted as ``morphisms'' betw…
