摘要：

We discuss an inflation model, in which the inflation is driven by a single scalar field with exponential potential on a warped DGP brane. In contrast to the power law inflation in the standard model, we find that the inflationary phase can exit spontaneously without any mechanism. The running of the index of the scalar perturbation spectrum can take a large enough value to match the observation data, while other parameters are in a reasonable region.
