We investigate the validity of the generalized second law of thermodynamics, in the
cosmological scenario where dark energy interacts with both dark matter and radiation …

We investigate the holographic dark energy scenario with a varying gravitational constant, in
flat and non-flat background geometry. We extract the exact differential equations …

We use observational data from Type Ia Supernovae (SN), Baryon Acoustic Oscillations
(BAO), Cosmic Microwave Background (CMB) and observational Hubble data (OHD), and …

In this paper, after reconstructing the redshift evolution of the Hubble function by adopting
Gaussian process techniques, we estimate the best-fit parameters for some flat Friedmann …

In this paper, we first obtain the energy density by the approach of the new agegraphic dark
energy model, and then the f (T, B) gravity model is studied as an alternative to the dark …

We have considered an action of the form T+ f (T)+ L m describing Einstein's gravity plus a
function of the torsion scalar. By considering an exact power-law solution we have obtained …

In the present work we investigate the cosmological implications of the entropy-corrected
holographic dark-energy (ECHDE) density in the Gauss-Bonnet framework. This is …

We examine the validity of the generalized second law of thermodynamics in a non-flat
universe in the presence of viscous dark energy. First we assume that the universe is filled …

We consider the new agegraphic model of dark energy with a varying gravitational constant,
G, in a non-flat universe. We obtain the equation of state and the deceleration parameters for …

Recently f (T) modified teleparallel gravity where T is the torsion scalar has been proposed
as the natural gravitational alternative for dark energy. We perform a detailed dynamical …
