Intermediate inflation on the brane and warped DGP models

Understand

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.
