At arbitrary parahoric level, the reduced special fiber of the GU(1,n−1) Rapoport-Zink space is stratified by closures of fine Deligne-Lusztig varieties, with incidence controlled by Bruhat-Tits indices and n−m+1 J(E)-orbits of irreducible components.

The Bruhat-Tits stratification for basic unramified $GU(1,n-1)$ Rapoport-Zink spaces at arbitrary parahoric level
At arbitrary parahoric level, the reduced special fiber of the GU(1,n−1) Rapoport-Zink space is stratified by closures of fine Deligne-Lusztig varieties, with incidence controlled by Bruhat-Tits indices and n−m+1 J(E)-orbits of irreducible components.
