绝对Festues-Fontaine曲线上的G-丛

G-bundles on the absolute Fargues-Fontaine curve

Johannes Anschütz

摘要:

证明了绝对Fargues-Fontaine曲线上的向量丛范畴(更确切地说是Fargues-Fontaine曲线上的向量丛的$v$ -栈$\mathrm{Bun}_\mathrm{FF}$的离散代数闭域上的截面范畴)正则等价于同晶范畴.对于某些约化群$G$以及局部投射有限群的分类栈上的$\mathrm{Bun}_\mathrm{FF}$的截面,我们对绝对Fargue-Fontaine曲线上的“$G$ -丛”导出了类似的结果.

英文摘要:

We prove that the category of ``vector bundles on the absolute Fargues--Fontaine curve'' (more precisely the category of sections over some discrete algebraically closed field of the $v$-stack $\mathrm{Bun}_\mathrm{FF}$ of vector bundles on the Fargues--Fontaine curve) is canonically equivalent to the category of isocrystals. We deduce a similar result for ``$G$-bundles on the absolute Fargues--Fontaine curve'' for some reductive group $G$ as well as for sections of $\mathrm{Bun}_\mathrm{FF}$ over classifying stacks for locally profinite groups.
