Half-line eigenfunction estimates and stability of singular continuous spectrum
We consider discrete one-dimensional Schrödinger operators with strictly ergodic, aperiodic potentials taking finitely many values. The well-known tendency of these operators to have purely singular continuous spectrum of zero Lebesgue measure is further elucidated. We study stability of singular continuity with respect to local perturbations. Moreover, we provide a unified approach to both the...
متن کاملClosed Nodal Lines and Interior Hot Spots of the Second Eigenfunction of the Laplacian on Surfaces
We build a one–parameter family of S−invariant metrics on the unit disc with fixed total area for which the second eigenvalue of the Laplace operator in the case of both Neumann and Dirichlet boundary conditions is simple and has an eigenfunction with a closed nodal line. In the case of Neumann boundary conditions, we also prove that this eigenfunction attains its maximum at an interior point, ...
متن کاملMultilinear Eigenfunction Estimates and Global Existence for the Three Dimensional
— We study nonlinear Schrödinger equations, posed on a three dimensional Riemannian manifold M . We prove global existence of strong H solutions on M = S and M = S × S as far as the nonlinearity is defocusing and sub-quintic and thus we extend results of Ginibre-Velo and Bourgain who treated the cases of the Euclidean space R and the torus T = R/Z respectively. The main ingredient in our argume...
متن کاملOn Strichartz and Eigenfunction Estimates for Low Regularity Metrics
A bstract . We produce, for dimensions n ≥ 3, examples of wave operators for which the Strichartz estimates fail. The examples include both Lipschitz and C1,α metrics, for each 0 < α < 1, where by the latter we mean that the gradient satisfies a Hölder condition of order α. We thus conclude that, on the scale of Hölder regularity, an assumption of at least 2 bounded derivatives for the metric (...
متن کاملHalf-line eigenfunction estimates and singular continuous spectrum of zero Lebesgue measure
We consider discrete one-dimensional Schrödinger operators with strictly ergodic, aperiodic potentials taking finitely many values. The well-known tendency of these operators to have purely singular continuous spectrum of zero Lebesgue measure is further elucidated. We provide a unified approach to both the study of the spectral type as well as the measure of the spectrum as a set. We apply thi...
