论文摘要
在本文中，我们考虑了某些联合$ x（μ，b）$ offine deligne-lusztig品种的仿射标志品种，这些品种是在与与连接的还原组相关的shtukas的mod- $ p $降低的研究中出现的。在$μ$上的轻度假设下，但对该组没有进一步的限制，我们计算其尺寸，如果$ b $是最大的中性可接受的元素。
In this paper, we consider certain union $X(μ,b)$ of affine Deligne-Lusztig varieties in the affine flag variety that arises in the study of mod-$p$ reduction of Rapoport-Zink spaces and moduli spaces of shtukas associated to a connected reductive group. Under a mild hypothesis on $μ$, but no further restrictions on the group, we compute its dimension in the case where $b$ is the maximal neutrally acceptable element.
