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 on the Klein bottle one has $…

Critical potentials of the eigenvalues and eigenvalue gaps of Schrödinger operators

Ahmad El Soufi, Nazih Moukadem

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