In this review we consider in detail different theoretical topics associated with interaction in
the dark sector. We study linear and nonlinear interactions which depend on the dark matter …

This paper is a review on the observational Hubble parameter data that have gained
increasing attention in recent years for their illuminating power on the dark side of the …

The problem of the cosmic acceleration is here revisited by using the fact that the adiabatic
speed of sound can be assumed to be negligible small. Within the context of general …

In order to test the possible interaction between dark energy and dark matter, we investigate
observational constraints on a phenomenological scenario, in which the ratio between the …

Compared with the plentiful researches of the Hubble parameter and deceleration factor, the
third time derivative of the scale factor a (t) in the FRW cosmology, namely, the jerk …

We use Hubble parameter versus redshift data from Stern et al.(2010)[1] and Gaztañaga et
al.(2009)[2] to place constraints on model parameters of constant and time-evolving dark …

Using relatively complete observational data concerning four angular diameter distance
(ADD) measurements and combined SN+ GRB observations representing current luminosity …

Abstract We use the Markov Chain Monte Carlo method to investigate a global constraints
on the modified Chaplygin gas (MCG) model as the unification of dark matter and dark …

This book introduces the current state of research on dark energy. It consists of three parts.
The first part is for preliminary knowledge, including general relativity, modern cosmology …
