The categorical arithmetic local Langlands conjecture

Assume that GG is quasi-split over FF, equipped with a pinning (B,T,e)(B,T,e), and fix a non-trivial additive character ψ:FZ[μp]×\psi:F\to {\mathbb Z}_\ell[\mu_{p^\infty}]^\times. Let \LocG^\Loc_{\widehat{G}} be the stack of local Langlands parameters and let \Shvc(B(G),Λ)\Shv_c({\mathfrak B}(G),\Lambda) be the category of constructible sheaves on the stack of GG-bundles on the Fargues-Fontaine curve, with coefficients in Λ\Lambda. The categorical arithmetic local Langlands conjecture. There is a canonical equivalence of categories

LG:\Coh(\LocG^Λ)\Shvc(B(G),Λ).{\mathbb L}_G:\Coh(\Loc_{\widehat{G}}\otimes\Lambda)\cong\Shv_c({\mathfrak B}(G),\Lambda).

This is presented as a categorical form of arithmetic local Langlands, inspired by the global geometric Langlands conjecture; related formulations replace the constructible category by a larger sheaf category and impose support conditions.
