In this article we study the special fiber of the Rapoport–Zink space attached to a quaternionic unitary group. The special fiber is described using the so called Bruhat–Tits stratification and is intimately related to the Bruhat–Tits building of a split symplectic group. As an application we describe the supersingular locus of the related Shimura variety.

关于四元数酉 Rapoport-Zink 空间的 Bruhat-Tits 分层

在本文中，我们研究了连接到四元单一基团的 Rapoport-Zink 空间的特殊纤维。特殊纤维使用所谓的 Bruhat-Tits 分层来描述，并且与分裂辛群的 Bruhat-Tits 构建密切相关。作为一个应用，我们描述了相关 Shimura 品种的超奇异位点。
