抛物丛模空间上的对偶复形

Dualizing complexes on the moduli of parabolic bundles

Linus Hamann, Naoki Imai

AI总结:

该研究针对非阿基米德局部域上带抛物子群的连通约化群,明确了Fargues–Fontaine曲线抛物丛模叠的对偶复形的模特征表示,应用于Shimura簇特征识别、相关猜想证明及几何艾森斯坦函子计算。

摘要:

对于非阿基米德局部域$F$以及$F$上配有抛物子群$P$的连通约化群$G$,我们证明,Fargues–Fontaine曲线上$P$-丛的模叠$\text{Bun}_P$上的对偶复形可以通过$P$的模特征明确描述。作为应用,我们确定了局部和整体Shimura簇理论中出现的各种特征,证明了Hodge–Newton可约情形下的Harris–Viehmann猜想,并对一般抛物群的几何艾森斯坦函子进行了若干计算。

英文摘要:

For a non-archimedean local field $F$ and a connected reductive group $G$ over $F$ equipped with a parabolic subgroup $P$, we show that the dualizing complex on $\mathrm{Bun}_P$, the moduli stack of $P$-bundles on the Fargues--Fontaine curve, can be described explicitly in terms of the modulus character of $P$. As applications, we identify various characters appearing in the theory of local and global Shimura varieties, show the Harris--Viehmann conjecture in the Hodge--Newton reducible case, and carry out some computations of the geometric Eisenstein functors for general parabolics.
