| Abstract: | We explore the predictions of a class of dark energy models, quinstant dark energy, concerning the structure formation in
the Universe, both in the linear and non-linear regimes. Quinstant dark energy is considered to be formed by quintessence and a negative cosmological constant. We conclude that these models give good predictions for structure formation in the linear regime, but fail to do so in the
non-linear one, for redshifts larger than one. |
