Abstract

We reconstruct the potential of minimally coupling inflation model which produces small value of the tensor-scalar ratio. In these inflation models, tensor-scalar ratio is proportional to 1/N² scalar spectral index is in good agreement with recent cosmological observations, in which N is the e-folding number and p is a positive number. We also reconstruct f(R) gravity inflation from small tensor-tensor ratio.
