Conjectured regularity for reciprocal-exponential quasi-de Sitter scale factors
Consider the quasi-de Sitter scale factor … Here $C^k$ extendibility means extendibility of the associated spacetime metric with $k$ continuous derivatives. Reciprocal-exponential…

Reflected-extension conjecture for extendible quasi-de Sitter spacetimes
Let a quasi-de Sitter spacetime admit an extension beyond its past boundary. A reflected extension is an extension obtained by extending the spacetime in a manner analogous to the…

Conjectured regularity for quasi-de Sitter scale factors of the form $e^t+e^{nt}$
Consider the quasi-de Sitter scale factor … Here $C^k$ extendibility refers to extendibility of the associated spacetime metric across the initial singularity with $k$ continuous d…
