Extension of the EGS theorem to metric and Palatini f(R) gravity
نویسنده
چکیده
By using the equivalence between metric and Palatini f(R) (or “modified”) gravities with ω = 0,−3/2 Brans-Dicke theories, it is shown that the EhlersGeren-Sachs theorem of general relativity is extended to modified gravity. In the case of metric f(R) gravity studied before, this agrees with previous literature.

We reply to a comment by Capozziello and Vignolo about the Cauchy problem of Palatini f(R) gravity. PACS numbers: 04.50.+h, 04.20.Ex, 04.20.Cv, 02.30.Jr In [1] Capozziello and Vignolo comment on Ref. [3], which discusses the Cauchy problem of metric and Palatini f(R) gravity (see also [2]). The contentious issue is Palatini f(R) gravity in vacuo. Ref.

متن کاملA no-go theorem for polytropic spheres in Palatini f(R) gravity
Non-vacuum static spherically-symmetric solutions in Palatini f(R) gravity are examined. It is shown that for generic choices of f(R), there are commonly-used equations of state for which no satisfactory physical solution of the field equations can be found within this framework, apart from in the special case of General Relativity, casting doubt on whether Palatini f(R) gravity can be consider...
متن کاملCurvature scalar instability in f(R) gravity
An instability in the presence of matter in theories of gravity which include a 1/R correction in the gravitational action has been found by Dolgov and Kawasaki. In the present paper this instability is discussed for f(R) gravity in general. We focus on the Palatini formalism of the theory and it is shown that no such instability occurs in this version of f(R) gravity. The reasons for the appea...
متن کاملStability of Palatini-f(R) cosmology
The evolution of linear cosmological perturbations in modified theories of gravity is investigated assuming the Palatini formalism. It has been discussed about the stability problem in this model based on the equivalence between f(R) gravity and the scalar tensor theory. However, we study this problem in the physical frame where the matter is minimally coupled. In general, the stability of the ...
متن کاملA ug 2 01 3 Hybrid modified gravity unifying local tests , galactic dynamics and late - time cosmic acceleration ∗
The non-equivalence between the metric and Palatini formalisms of f(R) gravity is an intriguing feature of these theories. However, in the recently proposed hybrid metric-Palatini gravity, consisting of the superposition of the metric Einstein-Hilbert Lagrangian with an f(R) term constructed à la Palatini, the “true” gravitational field is described by the interpolation of these two non-equival...
