Topological entropy for some isotropic cosmological models
A. Yu. Kamenshchik, I. M. Khalatnikov S. V. Savchenko, A. V. Toporensky
The chaotical dynamics is studied in different Friedmann-Robertson- Walker cosmological models with scalar (inflaton) field and hydrodynamical matter. The topological entropy is ca…
CMB Polarization During the Secondary Ionization of Matter
M. V. Sazhin, A. V. Toporensky
The cosmic microwave background (CMB) polarization, whose experimental detection must become the next natural step in the study of the CMB radiation, depends on the dynamics of hyd…
Simplest cosmological model with the scalar field
A. Yu. Kamenshchik, I. M. Khalatnikov, A. V. Toporensky
We investigate the simplest cosmological model with the massive real scalar non-interacting inflaton field minimally coupled to gravity. The classification of trajectories in close…
