Resumen
Nowadays many observational data suggest that the universe is undergoing an accelerated
expansion. However, several fundamental questions about the mechanism behind cosmic ac
celeration remain unanswered. Among these open questions, the possibility of a non-minimal
coupling between the two major energy components in the universe, i.e. the dark matter and the
dark energy, has been widely investigated in order to answer some of these issues. In this work,
we study the original model proposed by Wang and Meng, which is based on the interaction
among dark components of the universe. As a matter of fact, this approach is a phenomenologi
cal attempt to alleviate the so-called coincidence problem, being the gist, the interactions in the
dark sector.
