The Maslov index and some applications to dispersion relations in curved space times
Juliana Osorio Morales, Osvaldo Santillán
The aim of the present work is to generalize the results given in |81] to a generic situation for causal geodesics. It is argued that these results may be of interest for causality…
About apparent superluminal drives in generic gravity theories
J. Osorio Morales, O. Santillán
As is well known, there exists warp drives in GR, such as the Alcubierre bubbles, which achieve an apparent faster than light travel \cite{alcubierre}. A result due to Gao and Wald…
About the Cauchy problem in Stelle's quadratic gravity
J. Osorio Morales, O. Santillán
The focus of the present work is on the Cauchy problem for the quadratic gravity models introduced in \cite{stelle}-\cite{stelle2}. These are renormalizable higher order derivative…
Gauss-Bonnet models with cosmological constant and non zero spatial curvature in
Juan M. Armaleo, J. Osorio Morales, O. Santillan
In the present paper the possibility of eternal universes in Gauss-Bonnet theories of gravity in four dimensions is analysed. It is shown that, for zero spatial curvature and zero…
