Hawking's singularity theorem for -metrics
Michael Kunzinger, Roland Steinbauer, Milena Stojkovic +1
We provide a detailed proof of Hawking's singularity theorem in the regularity class , i.e., for spacetime metrics possessing locally Lipschitz continuous first derivative…
A regularisation approach to causality theory for -Lorentzian metrics
Michael Kunzinger, Roland Steinbauer, James A. Vickers +1
We show that many standard results of Lorentzian causality theory remain valid if the regularity of the metric is reduced to . Our approach is based on regularisations of…
The exponential map of a -metric
Michael Kunzinger, Roland Steinbauer, Milena Stojkovic
Given a pseudo-Riemannian metric of regularity on a smooth manifold, we prove that the corresponding exponential map is a bi-Lipschitz homeomorphism locally around any po…
