Spherically symmetric inextendibility of weak null singularities with Christoffel symbols in
Peter Cameron, Jan Sbierski
Motivated by the strong cosmic censorship conjecture in general relativity, we prove the inextendibility of spherically symmetric weak null singularities as spherically symmetric L…
A note on the instability of the Kerr Cauchy horizon under linearised gravitational perturbations
Jan Sbierski
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 o…
The formation of a weak null singularity in the interior of generic rotating black holes
Jonathan Luk, Jan Sbierski
Given a characteristic initial value problem with smooth data representing a dynamical event horizon settling down to that of Kerr in the subextremal, strictly rotating range with…
On the uniqueness of continuous spacetime extensions in 1+1 dimensions with applications to weak null singularities
Peter Cameron, Jan Sbierski
Motivated by weak null singularities in black hole interiors, we study 1+1 dimensional Lorentzian manifolds which admit a continuous spacetime extension across a null bound…
Lipschitz inextendibility of weak null singularities from curvature blow-up
Jan Sbierski
We prove the -inextendibility of weak null singularities without any symmetry assumptions. The proof introduces a new strategy to infer $C^{0,1}_{\mathrm{lo…
The -inextendibility of a class of FLRW spacetimes
Jan Sbierski
This paper studies the singularity structure of FLRW spacetimes without particle horizons at the -level of the metric. We show that in the case of constant spatial curvature $…
