The renormalized affine-flag localization conjecture

From papers

Let Op Op be the space of opers with nilpotent singularity, let \tN/\cG\tN/\cG be the nilpotent-cone quotient, and let

Op\arrowtimes\tN/\cG\bDf(\fD(\FlGaff)\critmod)Op\underset{\tN/\cG}\arrowtimes \bD^f(\fD(\Fl^{\operatorname{aff}}_G)_\crit\operatorname{mod})

be the ind-completed categorical base change. Let

Γ\Fl,Op:Op\arrowtimes\tN/\cG\bDf(\fD(\FlGaff)\critmod)\bDren(\hg\critmod\nilp)\Gamma_{\Fl, Op}: Op\underset{\tN/\cG}\arrowtimes \bD^f(\fD(\Fl^{\operatorname{aff}}_G)_\crit\operatorname{mod})\to\bD_{\mathrm{ren}}(\hg_\crit\operatorname{mod}_\nilp)

be the extended global-sections functor. Renormalized localization conjecture. This functor is an equivalence of categories and is exact. The paper proves full faithfulness and an equivalence on the I0I^0-equivariant subcategories, leaving essential surjectivity for the ambient categories conjectural.
