摘要: The effects of Hawking radiation on the evolution universe are examined in context chaotic inflationary models. Since inflation will not end if dominates energy density, a constraint can be derived which relates density massless states to Hubble parameter during period. form this shows that particle theories having larger values near Planck mass more vulnerable flatness problem. A model an expanding is constructed despite domination passive gravitational by radiation, gauge-invariant amplitude metric perturbations significantly decreased its presence. Some issues arising from necessity pre-inflationary radiation-dominated phase discussed.
