Wavenumber-explicit convergence of the $h p$ -FEM for the full-space heterogeneous Helmholtz equation with smooth coefficients

David Lafontaine, Euan A. Spence, Jared Wunsch

A convergence theory for the $h p$ -FEM applied to a variety of constant-coefficient Helmholtz problems was pioneered in the papers [Melenk-Sauter, 2010], [Melenk-Sauter, 2011], [Est…

Scattering for critical radial Neumann waves outside a ball

Thomas Duyckaerts, David Lafontaine

We show that the solutions of the three-dimensional critical defocusing nonlinear wave equation with Neumann boundary conditions outside a ball and radial initial data scatter. Thi…
