Abstract: The set of irreducible components of an affine Deligne-Lusztig variety is interesting for many applications related to Shimura varieties. We report our recent work studying this set, joint with Rong Zhou and Xuhua He-Rong Zhou. As an application, we deduce a formula for the number of irreducible components in the basic Newton stratum in Shimura varieties.
