Inflationary attractors in F(R) gravity
In this letter we shall demonstrate that the viable F(R) gravities can be classified mainly into two classes of inflationary attractors, either the R2 attractors or the α-attractors. To show this, we shall derive the most general relation between the tensor-to-scalar ratio r and the spectral index o...
