Multiple-mirror conjecture for transpolar VEX multitopes

Let (DX,DX)(\mathcal{D}^{\star}_X,\mathcal{D}_X) be a transpolar pair of VEX multitopes. A center-enclosing sub-simplex reduction is a pair of lattice simplices (ΔDX,DX)(\Delta\subset\mathcal{D}^{\star}_X,\nabla\subset\mathcal{D}_X). Multiple-mirror conjecture. Multiple mirrors specified by all such center-enclosing sub-simplex reductions are special cases of the mirror mapping extended to anticanonical hypersurfaces in the torus manifolds associated with the full multifans spanned by (DX,DX)(\mathcal{D}^{\star}_X,\mathcal{D}_X). The construction predicts a combinatorial network of mirror pairs whose size and variety grow with the complexity of the multitope pair; its general status is open.
