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 ${\square }_{g_{M,a}}\Psi =\epsilon \mathbf{B}\Psi$ on the exterior of a fixed subextremal Kerr spacetime $\left(\mathcal{M},g_{M,a}\righ…
