Maximizers in Lipschitz spacetimes are either timelike or null
Melanie Graf, Eric Ling
We prove that causal maximizers in spacetimes are either timelike or null. This question was posed in [17] since bubbling regions in spacetimes () can prod…
Milne-like spacetimes and their role in Cosmology
Eric Ling
Milne-like spacetimes are a class of FLRW models which admit spacetime extensions through the big bang. The boundary of a Milne-like spacetime can be identified with a null c…
Topology and singularities in cosmological spacetimes obeying the null energy condition
Gregory J. Galloway, Eric Ling
We consider globally hyperbolic spacetimes with compact Cauchy surfaces in a setting compatible with the presence of a positive cosmological constant. More specifically, for 3+1 di…
Timelike completeness as an obstruction to -extensions
Gregory J. Galloway, Eric Ling, Jan Sbierski
The study of low regularity (in-)extendibility of Lorentzian manifolds is motivated by the question whether a given solution to the Einstein equations can be extended (or is maxima…
