Existence of singularities in two-Kerr black holes
Piotr T. Chruściel, Michał Eckstein, Luc Nguyen +1
We show that the angular momentum - area inequality 8π|J| =< A for weakly stable minimal surfaces would apply to (I^+)-regular many-Kerr solutions, if any existed. Hence we remove…
On Lorentzian causality with continuous metrics
Piotr T. Chruściel, James D. E. Grant
We present a systematic study of causality theory on Lorentzian manifolds with continuous metrics. Examples are given which show that some standard facts in smooth Lorentzian geome…
Elements of causality theory
Piotr T. Chruściel
These notes present some elements of causality theory. While they are not as complete as other treatments of the topic, there is some originality in that the whole approach is base…
A lower bound for the mass of axisymmetric connected black hole data sets
Piotr T. Chruściel, Luc Nguyen
We present a generalisation of the Brill-type proof of positivity of mass for axisymmetric initial data to initial data sets with black hole boundaries. The argument leads to a str…
