摘要
本文旨在为非阿基米德局部域上约化群的 Bruhat-Tits 理论中的非分歧下降提供一种替代方法。该方法在概念上似乎比 Bruhat 和 Tits 论文中的方法更为简单。

备注
The earlier version has been revised to improve the exposition, to add more results and more details. The conditions that the residue field is perfect and of dimension less than or equal to 1 has been removed from the earlier versions. A new section (section 4) has been added to discuss hyperspecial points and hyperspecial parahoric subgroups
