The coherent-constructible correspondence for smooth complete fans
The coherent-constructible correspondence for smooth complete fans
Let be a free abelian group of rank , let be its dual, and let be a smooth complete fan in . Let be the associated smooth toric variety, set , and define
where is the quotient map. Let be the fully faithful morphism to the dg category of constructible sheaves whose microsupports are contained in . The coherent-constructible correspondence. The morphism induces a quasi-equivalence of dg categories.
This is the coherent-constructible correspondence formulated by Fang–Liu–Treumann–Zaslow; its equivariant version was proved by them. The claim is known when is cragged or has dimension , while the general smooth complete case remains open.
