Extended Quintessence with non-minimally coupled phantom scalar field
Orest Hrycyna, Marek Szydlowski
We investigate evolutional paths of an extended quintessence with a non-minimally coupled phantom scalar field to the Ricci curvature. The dynamical system methods are used to…
Constraints on oscillating dark energy models
Aleksandra Kurek, Orest Hrycyna, Marek Szydlowski
The oscillating scenario of route to Lambda was recently proposed by us arXiv:0704.1651 as an alternative to a cosmological constant in a explanation of the current accelerating un…
Route to Lambda in conformally coupled phantom cosmology
Orest Hrycyna, Marek Szydlowski
In this letter we investigate acceleration in the flat cosmological model with a conformally coupled phantom field and we show that acceleration is its generic feature. We reduce t…
Paths of Friedmann-Robertson-Walker brane models
Marek Szydlowski, Orest Hrycyna
Dynamics of brane-world models of dark energy is reviewed. We demonstrate that simple dark energy brane models can be represented as 2-dimensional dynamical systems of a Newtonian…
