abstract

We pose the isospectral problem for the $p$-widths: Is a riemannian manifold $(M^n, g)$ uniquely determined by its $p$-widths, $\{\omega_p(M,g)\}_{p=1}^{\infty}$? We construct many counterexamples on $S^2$ using Zoll metrics and the fact that geodesic $p$-widths are given by unions of immersed geodesics.

  1. On Zoll Contact 5-Spheres

    math.SG 2025-09 conditional novelty 8.0 of 10

    Every Zoll contact form on the standard contact 5-sphere is strictly contactomorphic to a scaling of the standard Zoll form.

  2. The p-widths of $RP^2$

    math.DG 2025-01 conditional novelty 6.0 of 10

    The p-widths of (RP^2, g_std) are ω_p = 2π floor((1+sqrt(1+8p))/4), achieved by Z2-invariant polynomial sweepouts.
