Universal algorithms for computing spectra of periodic operators
Jonathan Ben-Artzi, Marco Marletta, Frank Rösler
Schrödinger operators with periodic (possibly complex-valued) potentials and discrete periodic operators (possibly with complex-valued entries) are considered, and in both cases th…
Global Strichartz estimates for the Dirac equation on symmetric spaces
Jonathan Ben-Artzi, Federico Cacciafesta, Anne-Sophie de Suzzoni +1
In this paper we study global-in-time, weighted Strichartz estimates for the Dirac equation on warped product spaces in dimension . In particular, we prove estimates for th…
Computing the Sound of the Sea in a Seashell
Jonathan Ben-Artzi, Marco Marletta, Frank Rösler
The question of whether there exists an approximation procedure to compute the resonances of any Helmholtz resonator, regardless of its particular shape, is addressed. A positive a…
Strichartz estimates for the Klein-Gordon equation in a conical singular space
Jonathan Ben-Artzi, Federico Cacciafesta, Anne-Sophie de Suzzoni +1
Consider a conical singular space with the metric , where the cross section is a compact -dimensional closed Riemanni…
Computing Scattering Resonances
Jonathan Ben-Artzi, Marco Marletta, Frank Rösler
The question of whether it is possible to compute scattering resonances of Schrödinger operators - independently of the particular potential - is addressed. A positive answer is gi…
Uniform convergence in von Neumann's ergodic theorem in the absence of a spectral gap
Jonathan Ben-Artzi, Baptiste Morisse
Von Neumann's original proof of the ergodic theorem is revisited. A uniform convergence rate is established under the assumption that one can control the density of the spectrum of…
