Strichartz and smoothing estimates for dispersive equations with magnetic potentials

P D'ancona, L Fanelli - Communications in Partial Differential …, 2008‏ - Taylor & Francis
We prove global smoothing and Strichartz estimates for the Schrödinger, wave, Klein–
Gordon equations and for the massless and massive Dirac systems, perturbed with singular …

Time decay of scaling critical electromagnetic Schrödinger flows

L Fanelli, V Felli, MA Fontelos, A Primo - Communications in Mathematical …, 2013‏ - Springer
We obtain a representation formula for solutions to Schrödinger equations with a class of
homogeneous, scaling-critical electromagnetic potentials. As a consequence, we prove the …

On pointwise decay of waves

W Schlag - Journal of Mathematical Physics, 2021‏ - pubs.aip.org
This paper introduces some of the basic mechanisms relating the behavior of the spectral
measure of Schrödinger operators near zero energy to the long-term decay and dispersion …

[کتاب][B] Topologically protected states in one-dimensional systems

C Fefferman, J Lee-Thorp, M Weinstein - 2017‏ - ams.org
We study a class of periodic Schrödinger operators, which in distinguished cases can be
proved to have linear band-crossings or “Dirac points”. We then show that the introduction of …

Dispersion estimates for one-dimensional Schrödinger and Klein–Gordon equations revisited

IE Egorova, EA Kopylova… - Russian Mathematical …, 2016‏ - iopscience.iop.org
It is shown that for a one-dimensional Schrödinger operator with a potential whose first
moment is integrable the elements of the scattering matrix are in the unital Wiener algebra of …

The Lp-boundedness of wave operators for fourth order Schrödinger operators on R4

A Galtbayar, K Yajima - J. Spectr. Theory, 2024‏ - content.ems.press
We prove that the wave operators of the scattering theory for the fourth order Schrödinger
operator 2 CV. x/on R4 are bounded in Lp. R4/for the set of p's of. 1; 1/depending on the kind …

The Lp-continuity of wave operators for higher order Schrödinger operators

MB Erdoğan, WR Green - Advances in Mathematics, 2022‏ - Elsevier
We consider the higher order Schrödinger operator H=(− Δ) m+ V (x) in n dimensions with
real-valued potential V when n> 2 m, m∈ N, m> 1. When n is odd, we prove that the wave …

Kato smoothing and Strichartz estimates for wave equations with magnetic potentials

P D'Ancona - Communications in Mathematical Physics, 2015‏ - Springer
Let H be a selfadjoint operator and A a closed operator on a Hilbert space H H. If A is H-
(super) smooth in the sense of Kato-Yajima, we prove that AH^-1 4 AH-1 4 is H H-(super) …
