The topological mirror partner conjecture for toric degenerations

From papers

Let YY be a smooth complete algebraic variety that is the generic fiber of a flat family with special fiber Y0Y_0, where Y0Y_0 is a complete intersection in a complete toric variety determined by a calibrated nef-partitioned framing. Let Y0Y_0^\vee be the corresponding ff-mirror partner, and write kZk_Z and mZm_Z for the relevant topological invariants. Topological mirror partner conjecture. There exists a partitioned ftv (X,a=kak)(X,\mathbf{a}=\sum_k\mathbf{a}_k) and a suitable resolution Y^0Y0\widehat{Y}_0^\vee\longrightarrow Y_0^\vee such that Y0Y_0^\vee is a topological mirror partner of YY, namely

kY^0=mYandkY=mY0.k_{\widehat{Y}_0^\vee}=m_Y\quad\text{and}\quad k_Y=m_{Y_0^\vee}.

The conjecture extends ff-mirror duality from toric complete intersections to varieties admitting toric degenerations. The source gives no resolution status or supporting theorem for these equalities.
