General dissipative coefficient in warm intermediate and logamediate inflation

الأصل · EN

We study a general form for the dissipative coefficient Γ(T,ϕ)=CϕTᵐ/ϕᵐ⁻¹ in the context of warm intermediate and logamediate inflationary universe models. We analyze these models in the weak and strong dissipative regimes. In the slow-roll approximation, we describe in great detail the characteristics of these models. In both regimes, we use recent data from the WMAP nine-year data and Planck data to constrain the parameters appearing in our models.
