Abstract:
In this work, we compute the precise late-time asymptotics for the scalar
field in the interior of a non-static subextreme Kerr black hole, based on
recent progress on deriving its precise asymptotics in the Kerr exterior
region. This provides a new proof of the generic
$H^1_{\text{loc}}$-inextendibility of the Kerr Cauchy horizon against scalar
perturbations that is first shown by Luk--Sbierski (J. Func. Anal., 2016). The
analogous results in Reissner--Nordstr\"{o}m spacetimes are also discussed.
