Abstract
AbstractWe provide a proof of a conjecture by Jakobson, Nadirashvili, and Toth stating that on an n-dimensional flat torus 𝕋n, and the Fourier transform of squares of the eigenfunctions |φ λ|2 of the Laplacian have uniform ln bounds that do not depend on the eigenvalue λ. The proof is a generalization of an argument by Jakobson, et al. for the lower dimensional cases. These results imply uniform bounds for semiclassical limits on 𝕋n+2. We also prove a geometric lemma that bounds the number of codimension-one simplices satisfying a certain restriction on an n-dimensional sphere Sn(λ) of radius √λ, and we use it in the proof.
