Non-minimally coupled scalar field cosmology on the phase plane
Orest Hrycyna, Marek Szydlowski
In this publication we investigate dynamics of a flat FRW cosmological model with a non-minimally coupled scalar field with the coupling term in the scalar field action.…
Universe from vacuum in loop-string cosmology
Jakub Mielczarek, Marek Szydlowski
In this paper we study the description of the Universe based on the low energy superstring theory modified by the Loop Quantum Gravity effects.This approach was proposed by De Risi…
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…
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…
Phantom cosmology as a scattering process
Marek Szydlowski, Orest Hrycyna, Adam Krawiec
We study the general chaotic features of dynamics of the phantom field modelled in terms of a single scalar field conformally coupled to gravity. We demonstrate that the dynamics o…
Phantom cosmologies
Mariusz P. Dabrowski, Tomasz Stachowiak, Marek Szydlowski
We discuss a class of phantom () cosmological models. Except for phantom we admit various forms of standard types of matter and discuss the problem of singularities…
Simple Dynamics on the Brane
Marek Szydlowski, Mariusz P. Dabrowski, Adam Krawiec
We apply methods of dynamical systems to study the behaviour of the Randall-Sundrum models. We determine evolutionary paths for all possible initial conditions in a 2-dimensional p…
