摘要
给定一个数域,我们在其上构造一个典范伽罗瓦叠,并证明其上同调提供了arXiv:1304.3292中引入的精细局部内视域与经典全局内视域之间的桥梁。作为特别应用,我们将支配Arthur-Selberg迹公式稳定化的典范阿代尔转移因子表示为归一化局部转移因子的乘积,我们给出了阿代尔L-包与相应S-群之间配对(基于局部情形下的猜想配对)的显式构造,该配对是描述约化群的离散自守谱的基本要素,并且我们给出了Arthur某些预期的证明。

v4: The global gerbe is now canonical (section 3.5). We have added a reference to a ramification result of Ta\"ibi (section 3.9) and a statement and proof of a result (Lemma 4.5.1) that was implicitly used in section 4.5. 79 pages
