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 $\Gamma \propto {\varphi }^n$, with $n=0$ or $n\ne 0$.
