Journal ArticleDOI
Reconstruction method of f ( R ) gravity for isotropic and anisotropic spacetimes
TL;DR: In this paper, the authors present the reconstruction method of $f(R)$ gravity for the homogeneous and anisotropic Bianchi-I spacetime, which was previously formulated only for homogenous and isotropic Friedmann-Lemaitre-Robertson-Walker spacetime.
Journal ArticleDOI
Dynamical equivalence of f (R ) gravity in Jordan and Einstein frames
TL;DR: In this article, the authors investigated the dynamics of gravity in the Jordan and the Einstein frames and showed that the necessary conditions for the existence of the Einstein frame are the same ones assuring the absence of the anisotropic singularities in Jordan frames.
Journal ArticleDOI
Cosmological Bounce and Some Other Solutions in Exponential Gravity
TL;DR: In this paper, the authors present some cosmologically relevant solutions using the spatially flat Friedmann-Lemaitre-Robertson-Walker (FLRW) spacetime in metric f (R ) gravity where the form of the gravitational Lagrangian is given by 1 α e α R.
Journal ArticleDOI
Dynamical properties of Bianchi-I spacetimes in f (R) gravity
TL;DR: In this paper, a dynamical analysis in terms of new expansion-normalized variables for homogeneous and anisotropic Bianchi-I spacetimes in gravity in the presence of a non-perfect fluid is presented.
Journal ArticleDOI
Causal horizons in a bouncing universe
TL;DR: In this paper, the authors address the issue related to the particle horizon problem in the bouncing universe models and present a toy example of a bouncing universe where they specify the conditions which dictate the presence of a particle horizon.
