Warm intermediate inflationary Universe model in the presence of a generalized Chaplygin gas

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 ) , and we describe the inflationary dynamics in the slow-ro...

Description
Summary: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 ) , 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 > H , and the conditions for the weak and strong dissipative regimes.
