Residue characteristic two presents additional diffi culties in the construction of these representations\, and even for classi cal groups\, our knowledge is incomplete. In this talk\, based on joint wo rk with Jessica Fintzen\, I'll explain how to overcome one of these diffic ulties: the exceptional behavior of the Heisenberg group and Weil represen tation in characteristic two. Time permitting\, I'll also explain how to o vercome a second difficulty: disconnected Lie-algebra centralizers.\n LOCATION:https://researchseminars.org/talk/NTBU/44/ END:VEVENT END:VCALENDAR
