Extension of the EGS theorem to metric and Palatini f(R) gravity
Valerio Faraoni
By using the equivalence between metric and Palatini f(R) (or "modified") gravities with omega=0, -3/2 Brans-Dicke theories, it is shown that the Ehlers-Geren-Sachs theorem of gene…
f(R) gravity: successes and challenges
Valerio Faraoni
We review the state of the art of f(R) theories of gravity (in their various formulations), which have been proposed as an explanation of the cosmic acceleration alternative to dar…
Palatini f(R) gravity as a fixed point
Valerio Faraoni
In the context of modified gravity, we point out how the Palatini version of these theories is singled out as a very special case corresponding to the unique fixed point of a trans…
Reconstructing the universe history, from inflation to acceleration, with phantom and canonical scalar fields
Emilio Elizalde, Shin'ichi Nojiri, Sergei D. Odintsov +2
We consider the reconstruction technique in theories with a single or multiple (phantom and/or canonical) scalar fields. With the help of several examples, it is demonstrated expli…
