 Orateur(s) Sascha ORLIK - University of Leipzig, Titre Period domains over finite fields and Deligne-Lusztig varieties. Date 06/03/2008 Horaire 14:00 à 15:00 Résume Period domains over finite fields are Zariski-open subsets of flag varieties defined by a semi-stability condition. They were introduced and discussed by M. Rapoport in his paper Period domains over finite and local fields''. In this talk I want to discuss their relationship to Deligne-Lusztig varieties and their fundamental groups. Salle Adresse
