Cosmological models with bulk viscosity in the presence of particle creation
Published in Kluwer Academic/Plenum Publishers
Volume: 29
Issue: 4
Pages: 435 - 443
The effect of bulk viscosity, with a time varying bulk viscous coefficient, on the evolution of FRW models is investigated in the context of open thermodynamic systems, which allows for particle creation. It is seen that, by choosing an appropriate function for particle creation, the models presented exhibit non-singular beginnings.
