Warm-Chaplygin inflationary universe model

Abstract

Warm inflationary universe models in the context of a Chaplygin gas equation are studied. General conditions required for these models to be realizable are derived and discussed. By using a chaotic potential we develop models for a dissipation coefficient of the form Γ ∝ φ{symbol}n, with n = 0 or n ≠ 0. © 2008 Elsevier B.V. All rights reserved.
