Query: Inflation on a Warped Dvali-Gabadadze-Porrati Brane   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 standard model, we find that the inflationary phase
can exit spontaneously without any mechanism. The running of the index of
scalar perturbation spectrum can take an enough large value to match the
observation data, while other parameters are in a reasonable region.
