Abstract

A warm inflationary Universe in the Randall–Sundrum II model during intermediate inflation is studied. For this purpose, we consider the general form for the dissipative coefficient (Formula presented.), and also we analyze this inflationary model in the weak and strong dissipative regimes. We study the evolution of the Universe under the slow-roll approximation and find solutions to the full effective Friedmann equation in the brane-world framework. In order to constrain the parameters in our model, we consider the recent data from the BICEP2 to Planck 2015 data together with the necessary condition for warm inflation T>H, and also the condition from the weak (or strong) dissipative regime.
