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…

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…
