Viscous Dark Energy Models with Variable G and Lambda

Arbab I. Arbab

We consider a cosmological model with bulk viscosity ( $η$ ) and variable cosmological $(Λ \propto ρ^{- α}, α = const.$ ) and gravitational ( $G$ ) constants. The model exhibits many in…

Phantom Energy with Variable G and Lambda

Arbab I. Arbab

We have investigated a cosmological model of a phantom energy with a variable cosmological constant ( $Λ$ ) depending on the energy density ( $ρ$ ) as $Λ \propto ρ^{- α}$ , $α = const.$ …

Cosmological Models in the Generalized Einstein Action

Arbab I. Arbab

We have studied the evolution of the Universe in the generalized Einstein action of the form $R + β R^{2}$ , where $R$ is the scalar curvature and $β = const.$ . We have found exact cos…
