Stability of the expanding region of Kerr de Sitter spacetimes
Grigorios Fournodavlos, Volker Schlue
We prove the nonlinear stability of the cosmological region of Kerr de Sitter spacetimes. More precisely, we show that solutions to the Einstein vacuum equations with positive cosm…
Scattering for wave equations with sources close to the lightcone and prescribed radiation fields
Hans Lindblad, Volker Schlue
We construct solutions with prescribed radiation fields for wave equations with polynomially decaying sources close to the lightcone. In this setting, which is motivated by semi-li…
Optical functions in de Sitter
Volker Schlue
This paper addresses pure gauge questions in the study of (asymptotically) de Sitter spacetimes. We construct global solutions to the eikonal equation on de Sitter, whose level set…
Scattering from infinity for semilinear wave equations satisfying the null condition or the weak null condition
Hans Lindblad, Volker Schlue
We show global existence backwards from scattering data at infinity for semilinear wave equations satisfying the null condition or the weak null condition. Semilinear terms satisfy…
On "hard stars" in general relativity
Grigorios Fournodavlos, Volker Schlue
We study spherically symmetric solutions to the Einstein-Euler equations which model an idealized relativistic neutron star surrounded by vacuum. These are barotropic fluids with a…
Decay of the Weyl curvature in expanding black hole cosmologies
Volker Schlue
This paper is motivated by the non-linear stability problem for the expanding region of Kerr de Sitter cosmologies in the context of Einstein's equations with positive cosmological…
