Homogeneous Gödel-type solutions in hybrid metric-Palatini gravity
Janilo Santos, Marcelo J. Reboucas, Antônio F. F. Teixeira
[Abridged] If gravitation is to be described by a hybrid metric-Palatini gravity theory there are a number of issues that ought to be examined in its context, incl…
The virial theorem in Eddington-Born-Infeld gravity
Noelia S. Santos, Janilo Santos
We consider the possibility that the Eddington-Born-Infeld (EBI) modified gravity provides an alternative explanation for the mass discrepancy in clusters of galaxies. For this pur…
Palatini approach to modified f(R) gravity and its bi-metric structure
Janilo Santos, Crislane de Souza Santos
f(R) gravity theories in the Palatini formalism has been recently used as an alternative way to explain the observed late-time cosmic acceleration with no need of invoking either d…
Impedance of rigid bodies in one-dimensional elastic collisions
Janilo Santos, Bruna P. W. de Oliveira, Osman Rosso Nelson
In this work we study the problem of one-dimensional elastic collisions of billiard balls, considered as rigid bodies, in a framework very different from the classical one presente…
