A dimension formula of closed affine Deligne-Lusztig varieties of parahoric level (2406.17765v1)
Published 25 Jun 2024 in math.RT, math.AG, and math.NT
Abstract: We establish a dimension formula for certain union $XG(\mu,b)_J$ of affine Deligne-Lusztig varieties associated to arbitrary parahoric level structures of split reductive groups, under certain genericity hypotheses.
