| Description |
The evolution of matter density perturbations in the two-component model of the Universe filled with dark energy (DE) and dust-like matter (M) is considered. We have analysed it for two kinds of DE with ω ≠ −1: a) an unperturbed energy density and b) a perturbed one (uncoupled with the matter). For these cases, the linear equations for the evolution of the gauge-invariant amplitudes of matter density perturbations are presented. It is shown that, in the case of the unperturbed energy density of DE, the amplitude of matter density perturbations increases slightly faster than in the second case.
