This is the 2nd edition of a highly successful title on thisfascinating and complex subject.
Concentrating primarily on thetheory behind the origin and the evolution of the universe …

Recent cosmological observations have posed a challenge for traditional theories of gravity:
what is the force driving the accelerated expansion of the universe? What if dark energy or …

We study the spherical collapse model for several dark-energy scenarios using the fully non-
linear differential equation for the evolution of the density contrast within homogeneous …

We study the growth of perturbations in an expanding Newtonian universe with Bose-
Einstein condensate (BEC) dark matter. We first ignore special relativistic effects and derive …

We review dark energy models that can present non-negligible fluctuations on scales
smaller than Hubble radius. Both linear and nonlinear evolutions of dark energy fluctuations …

We study non-linear structure formation in the presence of dark energy. The influence of
dark energy on the growth of large-scale cosmological structures is exerted both through its …

We consider the global cosmological evolution and the evolution of the density contrast in
the Bose–Einstein condensate dark matter model, in the framework of a post-Newtonian …

We construct models of universe with a generalized equation of state p=(αρ+kρ^1+1/n)c^2
having a linear component and a polytropic component. Concerning the linear equation of …

We study two types of entropic-force models in a homogeneous, isotropic, spatially flat,
matter-dominated universe. The first type is a Λ (t) type similar to Λ (t) CDM (varying-lambda …
