Makeev's concurrent-planes conjecture for regular simplices

About 27 years old · traced to

Let F:Sn−1→RF:S^{n-1}\to\mathbb{R} be an odd function, and let Σn⊂Rn\Sigma_n\subset\mathbb{R}^n be a regular simplex of edge-length 11, with vertices v1,…,vn+1v_1,\ldots,v_{n+1}. For A∈SO(n)A\in SO(n) and each 1≤i<j≤n+11\leq i<j\leq n+1, consider the (n−1)(n-1)-plane

{x∈Rn∣⟨x,A(vj−vi)⟩=F(A(vj−vi))}.\{x\in\mathbb{R}^n\mid \langle x,A(v_j-v_i)\rangle=F(A(v_j-v_i))\}.

Makeev's conjecture. There exists an A∈SO(n)A\in SO(n) such that all n(n+1)/2n(n+1)/2 of these (n−1)(n-1)-planes are concurrent. The conjecture is a reformulation of Makeev's universal-cover conjecture in terms of continuous functions and supporting planes; the source gives no resolution.
