Constraints on Inflation in Einstein-Brans-Dicke Frame

General Relativity and Quantum Cosmology 2016-08-25 v2

Abstract

The density perturbation during inflation seeds the large scale structure. We consider both new inflation-type and chaotic inflation-type potentials in the framework of Einstein-Brans-Dicke gravity. The density perturbation gives strong constraints on the parameters in these potentials. For both potentials, the constraints are not much different from those obtained in the original inflationary models by using of Einstein gravity.
