Quantum theory of the Bianchi II model
Hervé Bergeron, Orest Hrycyna, Przemysław Małkiewicz +1
We describe the quantum evolution of the vacuum Bianchi II universe in terms of the transition amplitude between two asymptotic quantum Kasner-like states. For large values of the…

Dynamics and cosmological constraints on Brans-Dicke cosmology
Orest Hrycyna, Marek Szydlowski, Michal Kamionka
We investigate observational constraints on the Brans-Dicke cosmological model using observational data coming from distant supernovae type Ia, the Hubble function measureme…

Uniting cosmological epochs through the twister solution in cosmology with non-minimal coupling
Orest Hrycyna, Marek Szydlowski
We investigate dynamics of a flat FRW cosmological model with a barotropic matter and a non-minimally coupled scalar field (both canonical and phantom). In our approach we do not a…
