The basic locus of ramified unitary Shimura varieties of signature $(n-1,1)$ at maximal vertex level
Constructs Bruhat-Tits stratification for ramified unitary Rapoport-Zink space of signature (n-1,1) at vertex lattice level, proves normality, Cohen-Macaulayness and dimension formulas, and gives scheme-theoretic isomorphism to Deligne-Lusztig varieties.
