Logarithmic corrected F(R) gravity in the light of Planck 2015
In this Letter, we consider the theory of F(R) gravity with the Lagrangian density £=R+αR2+βR2lnβR. We obtain the constant curvature solutions and find the scalar potential of the gravitational field. We also obtain the mass squared of a scalaron in the Einstein's frame. We find cosmological p...
