Statistical hierarchy of varying speed of light cosmologies
Vincenzo Salzano, Mariusz P. Dabrowski
Variation of the speed of light is quite a debated issue in cosmology with some benefits, but also with some controversial concerns. Many approaches to develop a consistent varying…
Polish spaces of causal curves
Tomasz Miller
We propose and study a new approach to the topologization of spaces of (possibly not all) future-directed causal curves in a stably causal spacetime. It relies on parametrizing the…
Modelling spatial variations of the speed of light
Adam Balcerzak, Mariusz P. Dabrowski, Vincenzo Salzano
In this paper we extend a new method to measure possible variation of the speed of light by using Baryon Acoustic Oscillations and the Hubble function presented in our earlier pape…
Every timelike geodesic in anti--de Sitter spacetime is a circle of the same radius
Leszek M. Sokołowski, Zdzislaw A. Golda
We refine and analytically prove an old proposition due to Calabi and Markus on the shape of timelike geodesics of anti--de Sitter space in the ambient flat space. We prove that ea…
