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…
The -inextendibility of some spatially flat FLRW spacetimes
Eric Ling
Utilizing some of Sbierski's recent -inextendibility techniques [18], we prove the -inextendibility of a class of spatially flat FLRW spacetimes without particle horizons…
Anisotropic examples of inflation-generating initial conditions for the big bang
Eric Ling, Annachiara Piubello
The inflationary scenario, which states that the early universe underwent a brief but dramatic period of accelerated spatial expansion, has become the current paradigm of early uni…
Rigidity aspects of Penrose's singularity theorem
Gregory J. Galloway, Eric Ling
In this paper, we study rigidity aspects of Penrose's singularity theorem. Specifically, we aim to answer the following question: if a spacetime satisfies the hypotheses of Penrose…
On the discrete Dirac spectrum of general-relativistic hydrogenic ions with anomalous magnetic moment
Elie Kapengut, Michael K. -H. Kiessling, Eric Ling +1
The Reissner-Weyl-Nordström (RWN) spacetime of a point nucleus features a naked singularity for the empirically known nuclear charges and masses , wh…
