The wave equation on subextremal Kerr spacetimes with small non-decaying first order terms
Gustav Holzegel, Christopher Kauffman
We consider the perturbed covariant wave equation on the exterior of a fixed subextremal Kerr spacetime $\left(\mathcal{M},g_{M,a}\righ…

Global stability of Minkowski space for the Einstein-Maxwell-Klein-Gordon system in generalized wave coordinates
Christopher Kauffman, Hans Lindblad
We prove global existence for Einstein's equations with a charged scalar field for initial conditions sufficiently close to the Minkowski spacetime without matter. The proof relies…

A note on the wave equation on black hole spacetimes with small non-decaying first order terms
Gustav Holzegel, Christopher Kauffman
We present an elementary physical space argument to establish local integrated decay estimates for the perturbed wave equation on the exterior of the…
