The classical generalization of general relativity is considered as the gravitational alternative
for a unified description of the early-time inflation with late-time cosmic acceleration. The …

Over the past decade, f (R) theories have been extensively studied as one of the simplest
modifications to General Relativity. In this article we review various applications of f (R) …

We review the recent literature on modified theories of gravity in the Palatini approach. After
discussing the motivations that lead to consider alternatives to Einstein's theory and to treat …

In this paper we obtain topological static solutions of some kind of pure F (R) gravity. The
present solutions are two kind: first type is uncharged solution which corresponds with the …

The Noether symmetry of a generic f (R) cosmological model is investigated by utilizing the
behavior of the corresponding Lagrangian under the infinitesimal generators of the desired …

We investigate the dynamics of a neutral and a charged particle around a black hole in
modified gravity immersed in a magnetic field. Our focus is on the scalar-tensor-vector theory …

In this Letter, we consider the special case of F (R) gravity, in which F (R)= RN and obtain its
topological black hole solutions in higher dimensions. We show that, the same as higher …

Since the seminal work of Verlinde, the idea that gravity may be an emergent force of
entropic origin has gained widespread attention. Many generalizations of this key idea have …

We study the Hamiltonian formulation of f (R) theories of gravity both in metric and in Palatini
formalism using their classical equivalence with Brans-Dicke theories with a nontrivial …

We quantize a flat FRW cosmology in the context of the f (R) gravity by Noether symmetry
approach. We explicitly calculate the form of f (R) for which such symmetries exist. It is …
