The growth of matter perturbations in some scalar-tensor DE models
Radouane Gannouji, David Polarski
We consider asymptotically stable scalar-tensor dark energy (DE) models for which the equation of state parameter tends to zero in the past. The viable models are of the p…

On the growth of linear perturbations
David Polarski, Radouane Gannouji
We consider the linear growth of matter perturbations in various dark energy (DE) models. We show the existence of a constraint valid at between the background and dark energ…
