Warm inflation in the DGP brane-world model

Warm inflationary universe models on a warped Dvali-Gabadadze-Porrati brane are studied. General conditions required for these models to be realizable are derived and discussed. By using an effective exponential potential we develop models for constant and variable dissipation coefficient ratio r=Γ3H. We use recent astronomical observations for constraining the parameters appearing in our models.
