Black hole evolutions: Lessons from bifurcation theory
Ivan Booth, Graham Cox, Chiamaka Mary Okpala
We explore the role of the stability operator in regulating the evolution of marginally outer trapped surfaces (MOTSs). In 2005, Andersson, Mars and Simon showed that if the stabil…

Symmetry and instability of marginally outer trapped surfaces
Ivan Booth, Graham Cox, Juan Margalef-Bentabol
We consider an initial data set having a continuous symmetry and a marginally outer trapped surface (MOTS) that is not preserved by this symmetry. We show that such a MOTS is unsta…
