Novik–Zheng affine-stress support conjecture for simplicial spheres

About 3 years old · traced to

Let 2≤i≤d/22\leq i\leq d/2. Let Δ\Delta be either the boundary complex of a simplicial dd-polytope with its natural embedding pp, or a simplicial (d−1)(d-1)-sphere with a generic embedding pp. Assume that Δ\Delta has no missing faces of dimension at least d−i+1d-i+1. The affine-stress support conjecture. Every (i−1)(i-1)-face of Δ\Delta participates in some affine ii-stress on (Δ,p)(\Delta,p). In particular, the space of affine ii-stresses of (Δ,p)(\Delta,p) determines the (i−1)(i-1)-skeleton of Δ\Delta. The i=2i=2 case is known by the cited results, but all other cases remain wide open.
