Greatest least eigenvalue of the Laplacian on the Klein bottle

Ahmad El Soufi, Hector Giacomini, Mustapha Jazar

We prove the following conjecture recently formulated by Jakobson, Nadirashvili and Polterovich \cite{JNP}: For any Riemannian metric $g$ on the Klein bottle $K$ one has $…

Critical potentials of the eigenvalues and eigenvalue gaps of Schrödinger operators

Ahmad El Soufi, Nazih Moukadem

Let $M$ be a compact Riemannian manifold with or without boundary, and let $- Δ$ be its Laplace-Beltrami operator. For any bounded scalar potential $q$ , we denote by $λ_i (q)$ the $…

Eigenvalues of the Laplacian acting on $p$ -forms and metric conformal deformations

Bruno Colbois, Ahmad El Soufi

Let $(M, g)$ be a compact connected orientable Riemannian manifold of dimension $n \geq 4$ and let $λ_{k, p} (g)$ be the $k$ -th positive eigenvalue of the Laplacian $Δ_{g, p} = d d^{*} + d^{*} d$ …
