Cut locus smeariness conjecture for real projective spaces

About 7 years old · traced to

Let m≥2m\geq 2, and let FF and GG denote the Fréchet functions associated with the intrinsic and comparison distance settings, respectively, near the origin 00 in the real projective space RPm\mathbb{R}P^m. Cut locus smeariness conjecture. For every neighborhood UU of 00, there is an x∈Ux\in U such that

F(x)≠G(x).F(x)\neq G(x).

This would indicate that RPm\mathbb{R}P^m admits cut locus smeariness. The statement is motivated by the fact that cut locus smeariness can occur when the cut locus has dimension m−1m-1, but its resolution is not supplied here.
