Cosmological implications of the transition from the false vacuum to the true vacuum state
Aleksander Stachowski, Marek Szydlowski, Krzysztof Urbanowski
We study the cosmology with the running dark energy. The parametrization of dark energy with the respect to the redshift is derived from the first principles of quantum mechanics.…
Starobinsky cosmological model in Palatini formalism
Aleksander Stachowski, Marek Szydlowski, Andrzej Borowiec
We classify singularities in FRW cosmologies, which dynamics can be reduced to the dynamical system of the Newtonian type. This classification is performed in terms of geometry of…
Does the diffusion DM-DE interaction model solve cosmological puzzles?
Marek Szydlowski, Aleksander Stachowski
We study dynamics of cosmological models with diffusion effects modeling dark matter and dark energy interactions. We show the simple model with diffusion between the cosmological…
Dynamics of the diffusive DM-DE interaction--dynamical system approach
Zbigniew Haba, Aleksander Stachowski, Marek Szydlowski
We discuss dynamics of a model of an energy transfer between dark energy (DE) and dark matter (DM). The energy transfer is determined by a non-conservation law resulting from a dif…
