ENERGY CONDITIONS IN f(R) GRAVITY AND BRANS–DICKE THEORIES
ENERGY CONDITIONS IN f(R) GRAVITY AND BRANS–DICKE THEORIES
The equivalence between f(R) gravity and scalar–tensor theories is invoked to study the null, strong, weak and dominant energy conditions in Brans–Dicke theory. We consider the validity of the energy conditions in Brans–Dicke theory by invoking the energy conditions derived from a generic f(R) theory. The parameters involved are shown …
