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…

Conditions for the cosmological viability of f(R) dark energy models
Luca Amendola, Radouane Gannouji, David Polarski +1
We derive the conditions under which dark energy models whose Lagrangian densities f are written in terms of the Ricci scalar R are cosmologically viable. We show that the cosmolog…
