Dynamics of bulk viscous pressure effected inflation in braneworld scenario

The main goal of the present work is to examine the possible realization of warm chaotic inflation and logamediate inflation within the framework of a modified Chaplygin gas brane-world model. In this respect, the slow-roll parameters, number of e-folds, scalar-tensor power spectra, spectral indices, tensor–scalar ratio and running of scalar spectral index is being evaluated. These parameters are being analyzed for variable as well as constant dissipation and bulk viscous coefficients. Further, the trajectories among the inflationary parameters such as ns−ϕ,ns−ϕ,ns−r,ns−r,αs−ϕαs−ϕ and ns−αsns−αs are also developed to examine their behavior as well as physical cosmology. Some of results of inflationary parameters in all cases are: r   < 0.11, ns=0.96±0.025ns=0.96±0.025 and αs=−0.019±0.025αs=−0.019±0.025. It is interesting to mention here that the results of inflationary parameters are consistent with BICEP2, WMAP (7+9)(7+9) and Planck data.
