Batyrev--Borisov homological mirror symmetry conjecture

Let (Z,Zˇ)(Z,\check{Z}) be a Batyrev--Borisov mirror pair, with ZZ and Zˇ\check{Z} smooth subvarieties of Fano toric varieties XΣX_{\Sigma} and XΣˇX_{\check{\Sigma}} associated to dual nef partitions Δ=Δ1++Δr\Delta=\Delta_1+\dots+\Delta_r and =1++r\nabla=\nabla_1+\dots+\nabla_r, and centred refined triangulating functions hh and hˇ\check{h}. Write \mF\mF for the Fukaya category and DdgbD^b_{dg} for the dg-enhanced bounded derived category. Batyrev--Borisov HMS conjecture. There exist quasi-equivalences

\mF(Z)Ddgb(Zˇ),\mF(Zˇ)Ddgb(Z).\mF(Z)\cong D^b_{dg}(\check{Z}),\qquad \mF(\check{Z})\cong D^b_{dg}(Z).

This is presented as the ultimate goal of the paper and is intentionally somewhat imprecise. The preceding Hodge-number equalities provide evidence for mirror symmetry, but the stated categorical equivalences are not established in the source.
