Brane and warped Dvali–Gabadadze–Porrati inflationary universe models in the context of intermediate inflation are studied. In both models we consider that the energy density is a standard scalar field and we discuss the evolution of the universe during the slow-roll inflation. Also, we describe the conditions for these models. The corresponding Wilkinson Microwave Anisotropy Probe seven-year data are utilized to fix some parameters in our models. Our results are compared to those found in general relativity.
