Effects of second viscosity in cosmology

  • A. S. Potupa


It is shown that in homogeneous cosmological models which take viscosity into account there exist solutions realizing an interpolation between the Friedmann and stationary (steady-state) regimes. In a closed model a solution is obtained which corresponds to the regime of “compensation of curvature” (with radius increasing without bound). The problem of compensation of the singularity as t → 0 and also the choice of equations of state for early (hadron) stages of cosmological evolution in connection with the hydrodynamical theory of multiple creation of hadrons are discussed.
