Dynamics of perturbations in Gurzadyan-Xue cosmological models
نویسنده
چکیده
Perturbation theory within Newtonian approximation is presented for cosmological models with varying physical constants. Analytical solutions for perturbations dynamics are obtained for each Gurzadyan-Xue model with pressureless matter and radiation. We found that perturbations grow during entire expansion within GX models, including curvatureand vacuum-dominated stage when they cease to grow in the standard cosmological model.

Cosmological models with Gurzadyan-Xue dark energy
The formula for dark energy density derived by Gurzadyan and Xue provides a remarkable fit to the SN data, unlike numerous phenomenological dark energy scenarios where the corresponding value is postulated. We consider several cosmological models based on that formula and derive the cosmological equations for each case. It is shown that in all models source terms appear in the continuity equati...

We have derived the invariants of cosmological models with Gurzadyan-Xue dark energy, along with the solutions for any time dependent light speed and gravitational constant. The correspondence of the invariants with the separatrices found earlier for the GX-models in [4] is shown, and hence the basis of then detected hidden symmetry is now revealed. Solutions are derived both for radiation and ...

In the previous papers we derived cosmological equations for models with Gurzadyan-Xue dark energy, have performed their qualitative analysis and, particularly, have revealed a remarkable hidden invariance in the models with respect to the sepa-ratrix Ω sep in their phase portraits. Now, new analytic solutions for these models are obtained, showing additional symmetries at various curvatures. T...

We consider cosmological implications of the formula for the dark energy density derived by Gurzadyan and Xue [1] which predicts a value fitting the obervational one. Cosmological models with varying by time physical constants, namely, speed of light and gravitational constant and/or their combinations, are considered. In one of the models, for example, vacuum energy density induces effective n...
