Connected components of closed affine Deligne-Lusztig varieties for Res(E/F)GL(n)

摘要

Let F be a p-adic field and let E/F be a finite unramified extension. For the Weil restriction Res(E/F)GL(n) of the general linear group GL(n), we determine the connected components of closed affine Deligne-Lusztig varieties of arbitrary parahoric level. (C) 2019 Elsevier Inc. All rights reserved.
