Energy conditions in f(R)-gravity
J. Santos, J. S. Alcaniz, M. J. Reboucas +1
In order to shed some light on the current discussion about f(R)-gravity theories we derive and discuss the bounds imposed by the energy conditions on a general f(R) functional for…

Lookback time bounds from energy conditions
J. Santos, J. S. Alcaniz, M. J. Reboucas +1
In general relativity, the energy conditions are invoked to restrict general energy-momentum tensors on physical grounds. We show that in the standard Friedmann-Lemaitre-Robertson-…
