A note on exterior stability of isolated singularity formation for nonlinear wave equations
Istvan Kadar, Lionor Kehrberger
We study the stability of the exterior of Type I and Type II singularity formation for the wave maps equation in with and the power nonlinear wave equat…
Linear and nonlinear late-time tails on dynamical black hole spacetimes via time integrals
Dejan Gajic, Lionor Kehrberger
We prove the global leading-order late-time asymptotic behaviour of solutions to inhomogeneous wave equations on dynamical black hole exterior backgrounds that settle down to Schwa…
The Case Against Smooth Null Infinity V: Early-Time Asymptotics of Linearised Gravity Around Schwarzschild for Fixed Spherical Harmonic Modes
Lionor Kehrberger, Hamed Masaood
Starting from Post-Newtonian predictions for a system of infalling masses from the infinite past, we formulate and solve a scattering problem for the system of linearised gravi…
The Case Against Smooth Null Infinity III: Early-Time Asymptotics for Higher -Modes of Linear Waves on a Schwarzschild Background
Lionor M. A. Kehrberger
In this paper, we derive the early-time asymptotics for fixed-frequency solutions to the wave equation on a fixed Schwarzschild background () arisin…
