The Hawking-Penrose singularity theorem for $C^1$-Lorentzian metrics

Michael Kunzinger, Argam Ohanyan, Benedict Schinnerl +1

We extend both the Hawking-Penrose Theorem and its generalisation due to Galloway and Senovilla to Lorentzian metrics of regularity $C^1$. For metrics of such low regularity, two m…
