Ingalls–Kuznetsov equivalence conjecture for Artin–Mumford quartic double solids

About 7 years old · traced to

Let YY be a general Artin–Mumford quartic double solid, let Y′Y' be its blow-up at its 1010 singular points, and let XX be the Enriques surface associated to YY. Let AY′{\mathcal A}_{Y'} denote the residual category associated to Y′Y'. Ingalls–Kuznetsov conjecture. There is an equivalence

AY′≅Db(X).{\mathcal A}_{Y'}\cong\mathrm{D}^{\mathrm{b}}(X).

This conjecture proposes a categorical counterpart to the correspondence between general Artin–Mumford quartic double solids and their associated Enriques surfaces. It was proved by Hosono and Takagi.
