Toward reconstruction of dynamics of the Universe from distant supernovae type Ia
Marek Szydlowski, Wojciech Czaja
We demonstrate a model-independent method of estimating qualitative dynamics of an accelerating universe from observations of distant type Ia supernovae. Our method is based on the…

Stability of FRW Cosmology with Generalized Chaplygin Gas
Marek Szydlowski, Wojciech Czaja
We apply methods of dynamical systems to study the behaviour of universe dominated by the generalized Chaplygin gas. We reduce the dynamics to a 2-dimensional Hamiltonian system an…

Particle-Like Description in Quintessential Cosmology
Marek Szydlowski, Wojciech Czaja
Assuming equation of state for quintessential matter: , we analyse dynamical behaviour of the scale factor in FRW cosmologies. It is shown that its dynamics is formally eq…
