The Penrose singularity theorem, MOTS stability, and horizon topology in weighted spacetimes
Eric Ling, Argam Ohanyan, Eric Woolgar
We consider versions of the Penrose singularity theorem and the Hawking horizon topology theorem in weighted spacetimes that contain weighted versions of trapped surfaces, for arbi…
Vacuum cosmological spacetimes without CMC Cauchy surfaces
Eric Ling, Argam Ohanyan
In this article, we extend a construction of [6] to obtain a large class of vacuum cosmological spacetimes that do not contain any CMC Cauchy surfaces. The allowed spatial topologi…
Examples of cosmological spacetimes without CMC Cauchy surfaces
Eric Ling, Argam Ohanyan
CMC (constant mean curvature) Cauchy surfaces play an important role in mathematical relativity as finding solutions to the vacuum Einstein constraint equations is made much simple…
Hawking-type singularity theorems for worldvolume energy inequalities
Melanie Graf, Eleni-Alexandra Kontou, Argam Ohanyan +1
The classical singularity theorems of R. Penrose and S. Hawking from the 1960s show that, given a pointwise energy condition (and some causality as well as initial assumptions), sp…
