Compatibility of the global-space functor with the presheaf equivalence

About 6 years old · traced to

Let OrbSpc\mathrm{OrbSpc} be the category of orbispaces, let OrbSpc‾\overline{\mathrm{OrbSpc}} be its enlargement obtained by gluing cells under arbitrary maps, and let GloSpc\mathrm{GloSpc} be the category of global spaces. The paper considers an equivalence

OrbSpc‾≃GloSpc\overline{\mathrm{OrbSpc}}\simeq\mathrm{GloSpc}

constructed from results of Gepner--Henriques and Schwede. Global-space compatibility conjecture. The restriction of this equivalence to the full subcategory OrbSpc⊆OrbSpc‾\mathrm{OrbSpc}\subseteq\overline{\mathrm{OrbSpc}} coincides with the functor sending an orbispace XX to Emb⁡X(E,−)\operatorname{Emb}_X(E,-) for a faithful vector bundle EE over XX. This would identify the geometric global-space construction with the presheaf-theoretic equivalence.
