Closed-spectrum eigenvalue inequality conjecture for minimal submanifolds of spheres

About 5 years old · traced to

Let MnM^n be an nn-dimensional compact minimal submanifold of the unit sphere Sn+p(1)S^{n+p}(1), and let Λ‾j\overline{\Lambda}_j denote the eigenvalues of the closed Laplace–Beltrami problem on MnM^n. Closed-spectrum eigenvalue inequality conjecture. For the relevant positive integer jj,

∑k=1nΛ‾j+k≤(n+3)Λ‾j+Λ‾j2Λ‾j+1+n2.\sum_{k=1}^{n}\overline{\Lambda}_{j+k} \leq (n+3)\overline{\Lambda}_{j} +\frac{\overline{\Lambda}_{j}^{2}}{\overline{\Lambda}_{j+1}}+n^{2}.

The inequality is proposed as a universal estimate for closed eigenvalues on minimal submanifolds. The supplied statement does not specify the range of jj or provide resolution evidence.
