Dispersive estimates for wave and Schr\" odinger equations with a potential in non-trapping exterior domains

T Duyckaerts, JU Yang - arXiv preprint arXiv:2401.12608, 2024 - arxiv.org
We prove resolvent estimates for a Schr\" odinger operator with a short-range potential
outside an obstacle with Dirichlet boundary conditions. As a consequence, we deduce …

Scattering for critical wave equations with variable coefficients

SZ Looi, M Tohaneanu - Proceedings of the Edinburgh Mathematical …, 2021 - cambridge.org
We prove that solutions to the quintic semilinear wave equation with variable coefficients in
R 1+ 3 scatter to a solution to the corresponding linear wave equation. The coefficients are …
