ENERGY CONDITIONS CONSTRAINTS ON A CLASS OF f(R)-GRAVITY
ENERGY CONDITIONS CONSTRAINTS ON A CLASS OF f(R)-GRAVITY
We present and discuss the bounds from the energy conditions on a general f(R) functional form in the framework of metric variational approach. As a concrete application of the energy conditions to locally homogeneous and isotropic f(R)-cosmology, the recent estimated values of the deceleration and jerk parameters are used to …
