Abstract

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 $r=\frac{\Gamma}{3 H}$. We use recent astronomical observations for constraining the parameters appearing in our models.
