Abstract

A warm inflationary universe scenario on a warped Dvali-Gabadadze-Porrati brane during intermediate inflation is studied. We consider a general form for the dissipative coefficient Γ(T,φ) Tm/φm-1, and also study this model in the weak and strong dissipative regimes. We analyze the evolution of the Universe in the slow-roll approximation and find the exact solutions to the equations of motion. In both regimes, we utilize recent data from the BICEP2 experiment and also from the Planck satellite to constrain the parameters in our model in accordance with the theory of cosmological perturbations.
