Abstract
- In this paper, we investigate the holographic inflation in the framework of two gravitational theories like f (T) gravity, where T corresponds to the torsion scalar and DGP braneworld model which is based on the idea that our four-dimensional FRW universe located on five-dimensional manifold. The modified infrared cutoff is used to explore all the inflationary parameters as slow-roll parameters ( 1 , 2 , 3) , number of e -folds N , scalar spectral index n s , tensor-to-scalar ratio r and running of the scalar spectral index α s . Also, we investigate the behavior of inflationary parameters n s − N , α s − N , r − N , α s − n s and r − n s through graphical presentation. The behavior of these parameters shows the consistency with Planck data 2 0 1 8. [ABSTRACT FROM AUTHOR]
