Abstract
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 ${\rm Bun}_{\rm FF}$ 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 ${\rm Bun}_{\rm FF}$ over classifying stacks for locally profinite groups.
