Palatini f(R) gravity as a fixed point
نویسنده
چکیده
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 transformation involving a special conformal rescaling of the metric. This mathematical peculiarity signals deeply rooted problems which make the theory unphysical. PACS: 04.50+h, 04.20.Cv, 04.20.Fy, 04.90.+e.

A 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 کاملExtension of the EGS theorem to metric and Palatini f(R) gravity
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.
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...

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. [3] reduces the initial value problem of bo...
متن کامل2 00 3 The minimal curvature of the universe in modified gravity and conformal anomaly resolution of the instabilities Shin
We discuss the modified gravity which may produce the current cosmic acceleration of the universe and eliminates the need for dark energy. It is shown that such models where the action quickly grows with the decrease of the curvature define the FRW universe with the minimal curvature. It is required the infinite time to reach the minimal curvature during the universe evolution. It is demonstrat...
