- Abstract
A warm inflationary universe in the brane-world scenario is being studied by assuming the standard scalar and tachyon field models. For this purpose, the quartic potential () is being utilized which is ruled out by current data in cold inflation but in our models it is analyzed that it is in agreement with recent observational data. Moreover, the generalized form of dissipative coefficient is being considered. Within this setup, the inflationary parameters in the weak dissipative regime are being analyzed. It is observed that the ranges of our results of tensor-to-scalar ratio, scalar spectral index and running of spectral favor observational data like BICEP2, WMAP9 and Planck.
