A note on the instability of the Kerr Cauchy horizon under linearised gravitational perturbations
arXiv:2604.06283
Abstract
This note slightly strengthens the result of arXiv:2201.12295 on the linear instability of the Kerr Cauchy horizon. This strengthened result is used in the proof arXiv:2604.04877 of the non-linear instability of the Kerr Cauchy horizon.
