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…

Conformal Geodesics Cannot Spiral -- Erratum
Peter Cameron, Maciej Dunajski, Paul Tod
Wojciech Kamiński has provided a non real-analytic counterexample to our claim in [1] that conformal geodesics cannot spiral. This erratum illustrates how the proof of Lemma 4.6 [1…

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…
