Interpretation of bulk viscosity as the generalized Chaplygin gas
Marek Szydlowski, Adam Krawiec
The cosmological observations suggest that the presently accelerating universe should be filled by an exotic form of matter, violating the strong energy condition, of unknown natur…
Bifurcations in economic growth model with distributed time delay transformed to ODE
Luca Guerrini, Adam Krawiec, Marek Szydlowski
We consider the model of economic growth with time delayed investment function. Assuming the investment is time distributed we can use the linear chain trick technique to transform…
Bifurcations in Ratra-Peebles quintessence models and their extensions
Franciszek Humieja, Marek Szydlowski
We have used the dynamical system approach in order to investigate the dynamics of cosmological models of the flat Universe with a non-minimally coupled canonical and phantom scala…
From quantum unstable systems to the decaying dark energy: Cosmological implications
Aleksander Stachowski, Marek Szydlowski, Krzysztof Urbanowski
We consider a cosmology with decaying metastable dark energy and assume that a decay process of this metastable dark energy is a quantum decay process. Such an assumption implies a…
Polynomial Palatini cosmology -- dynamical system approach
Marek Szydlowski, Aleksander Stachowski
We investigate cosmological dynamics based on gravity in the Palatini formulation. In this study we use the dynamical system methods. We show that the evolution of the Fried…
Simple cosmological model with inflation and late times acceleration
Marek Szydlowski, Aleksander Stachowski
In the framework of polynomial Palatini cosmology, we investigate a simple cosmological homogeneous and isotropic model with matter in the Einstein frame. We show that in this mode…
