Perturbations of single-field inflation in modified gravity theory
In this paper, we study the case of single field inflation within the framework of modified gravity theory where the gravity part has an arbitrary form f(R). Via a conformal transformation, this case can be transformed into its Einstein frame where it looks like a two-field inflation model. However,...
