DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NTBU/1/">p-a
 dic Deligne--Lusztig spaces</a>\nby Alexander Ivanov (Ruhr-Universität Bo
 chum) as part of Boston University Number Theory Seminar\n\nLecture held i
 n CDS Room 365 in Boston University.\n\nAbstract\nI explain how to carry o
 ver some definitions and results from classical Deligne--Luzstig theory (f
 or reductive groups over finite fields) to a setup over p-adic fields. Mor
 e precisely\, I discuss p-adic Deligne--Lusztig spaces\, defined as certai
 n arc-sheaves on perfect algebras over the residue field\, as well as some
  of their geometric properties. In some cases\, one can determine the coho
 mology of these spaces\, and use it to construct smooth representations of
  p-adic reductive groups geometrically.\n
