ABSTRACT
Recent high-precision observations [3] have provided
strong evidence that the Universe is in a phase of accelerated expansion. In
the cosmological standard model with theory of gravity as General Relativity
(GR), this accelerating phase can be explain with a component of negative
pressure called Dark Energy. However, we do not have direct evidence of Dark
Energy until now. It has motivated alternative models[2]. The models are
modi_cations to the Einstein-Hilbert action. An important subset of these
models are called generalized gravity theories, and they are based on
non-linear lagrangians written in the generic form f(R), where f is a general
di_erentiable function of the Ricci scalar R.
