| Abstract: | We study Chaplygin gas as a candidate for inflation in the context of braneworld inflationary model. We investigate this model in the framework of the Randall–Sundrum type II, considering a original and generalized Chaplygin gas. We use inverse power law potential to examine the behavior of some inflationary spectrum parameters such as the spectral index ns, the ratio r and the running of the scalar spectral index dns/dlnk, our results are in agreement with recent observational data for a particular choice of e-folding number N and parameters space of the model. |
