Description
We discuss the warm inflation in the presence of standard scalar field model and modified Chaplygin gas in brane-world scenario. We consider weak and strong dissipative regimes with generalized dissipative coefficient. We extract various inflationary parameters. For example, we analyze the behavior of different ratios (ratio of dissipative co-efficient and Hubble parameter Γ/3H, ratio of temperature and Hubble parameter T/H, scalar-to-tensor ratio r) with respect to spectral index ns for the weak and strong dissipative regimes through parametric plotting. It is found that T/H and Γ/3H satisfied the required conditions in both dissipative regimes. It is also noted that the spectral index (ns) attain the range . It is remarked here that our results are consistence with observational data WMAP7, WMAP9, and recent Planck data. (paper)
