Low-frequency dispersive estimates for the wave equation in higher dimensions
نویسنده
چکیده
We prove dispersive estimates at low frequency in dimensions n ≥ 4 for the wave equation for a very large class of real-valued potentials, provided the zero is neither an eigenvalue nor a resonance. This class includes potentials V ∈ L∞(R) satisfying V (x) = O ( 〈x〉−(n+1)/2−ǫ ) , ǫ > 0.

متن کاملLow-frequency dispersive estimates for the Schrödinger group in higher dimensions
For a large class of real-valued potentials, V (x), x ∈ R, n ≥ 4 , we prove dispersive estimates for the low frequency part of e Pac, provided the zero is neither an eigenvalue nor a resonance of −∆+ V , where Pac is the spectral projection onto the absolutely continuous spectrum of −∆ + V . This class includes potentials V ∈ L(R) satisfying V (x) = O ( 〈x〉−(n+2)/2−ǫ ) , ǫ > 0. As a consequence...

متن کاملStrichartz Estimates for the Water-wave Problem with Surface Tension
We study dispersive properties of one-dimensional surface waterwaves under surface tension, based on the formulation of the problem as a nonlinear dispersive equation coupled with a transport-type equation. We establish a dispersion estimate on time scales depending on the size of the frequencies. We infer that, if s is large enough, then a solution u of the dispersive equation satisfies local-...
