Zonal states and improved bounds for eigenfunctions of magnetic Laplacians on hyperbolic surfaces

Ambre Chabert, Thibault Lefeuvre

We establish polynomially improved bounds for eigenfunctions of magnetic Laplacians on hyperbolic surfaces in the critical energy regime. We also show that, below the cr…

On the {} norms of spectral projectors on shrinking intervals: the cases of some spheres of revolution and of the Euclidean disk

Ambre Chabert, Yves Colin de Verdìère

Given a compact Riemannian surface , with Laplace-Beltrami operator , for , let be the spectral projector on the bandwidth $[λ-λ^{-\frac{1}{3}}…

Bounds for quasimodes with polynomially narrow bandwidth on surfaces of revolution

Ambre Chabert

Given a compact surface of revolution with Laplace-beltrami operator , we consider the spectral projector on a polynomially narrow frequency interval , whi…

Weakly turbulent solution to Schrödinger equation on the two-dimensional torus with real potential decaying at infinity

Ambre Chabert

We build a smooth time-dependent real potential on the two-dimensional torus, decaying as time tends to infinity in Sobolev norms along with all its time derivative, and we exhibit…
