We make a detailed study of matter density perturbations in both metric and Palatini formalisms. Considering general theories whose Lagrangian density is a general function, $f(R)$, of the Ricci

We study a model including a real scalar ﬁeld φ non-minimally coupled to F ( R ) gravity, which is conformally equivalent to an Einstein–Hilbert theory, involving two
For almost a hundred years now, Einstein’s General Relativity theory has played a pivotal role in our understanding of the Universe. The recent realization of the accelerated cosmic expansion,

In this paper, we consider F(R)=R+f(R) theory instead of Einstein gravity with conformal anomaly and look for its analytical solutions. Depending on the free parameters, one may obtain both uncharged

We consider an f(R) action that is non-minimally coupled to a massive scalar field. The model closely resembles scalar–tensor theory and by conformal transformation can be transformed to Einstein
