Warm intermediate inflationary Universe model in the presence of a Generalized Chaplygin Gas

preprint2016arXivOpen access

Abstract

A warm intermediate inflationary model in the context of Generalized Chaplygin Gas is investigated. We study this model in the weak and strong dissipative regimes, considering a generalized form of the dissipative coefficient Γ=Γ(T,ϕ)Γ=Γ(T,ϕ), and we describe the inflationary dynamics in the slow-roll approximation. We find constraints on the parameters in our model considering the Planck 2015 data, together with the condition for warm inflation T>HT>H, and the conditions for the weak and strong dissipative regimes.
