Besicovitch-type inequality for a geodesic and minimal hypersurface on higher-dimensional spheres

From papers

Let n>2n>2, and let (Sn,g)(S^n,g) be an nn-dimensional Riemannian sphere. A Besicovitch-type geodesic–hypersurface inequality asserts that there is a constant C(n)>0C(n)>0, depending only on the dimension nn, such that there exist a closed geodesic γ\gamma and a smooth closed embedded minimal hypersurface Nn1N^{n-1} satisfying

Length(γ)Voln1(Nn1)C(n)Vol(Sn,g).\operatorname{Length}(\gamma)\cdot\operatorname{Vol}_{n-1}(N^{n-1})\leq C(n)\cdot\operatorname{Vol}(S^n,g).

This is proposed as a second higher-dimensional analogue of the Besicovitch inequality, complementing the conjectured product bound for nn distinct closed geodesics. Its resolution status is not established in the supplied source.
