Resumen:

We summarize the cosmological analysis that we have performed recently for several f(R) gravity models, including the comparison of several equations of state (EOS) that have been proposed in the past and which are used to characterize the geometric dark energy. We introduce the corresponding covariant energy-momentum tensors from which the EOS can be obtained and briefly discuss their drawbacks and advantages. © 2015, World Scientific.
