在这篇文章中,我们从两个方面改进了我们的主要结果:首先,我们在CM扩张中允许分枝位置,在那里我们考虑关于某个特殊的极大紧子群的球面表示,通过建立和证明关于奇异光滑Rapoport-Zink空间的Kudla-Rapoport猜想的类似。其次,通过证明具有Drinfeld能级结构的么正Shimura簇的积分模型的某些上同调的一个更一般的消失结果,我们取消了对自同构表示的分裂位置的分支的限制。
In this article, we improve our main results from [LL21] in two directions: First, we allow ramified places in the CM extension at which we consider representations that are spherical with respect to a certain special maximal compact subgroup, by formulating and proving an analogue of the Kudla–Rapoport conjecture for exotic smooth Rapoport–Zink spaces. Second, we lift the restriction on the components at split places of the automorphic representation, by proving a more general vanishing result on certain cohomology of integral models of unitary Shimura varieties with Drinfeld level structures.
