Holographic inflation in f(T) and DGP braneworld

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 (epsilon(1), epsilon(2), epsilon(3)), number of e-folds N, scalar spectral index n(s), tensor-to-scalar ratio r and running of the scalar spectral index alpha s. Also, we investigate the behavior of inflationary parameters n(s) - N,alpha(s) - N,r - N,alpha(s) - n(s) and r - n(s) through graphical presentation. The behavior of these parameters shows the consistency with Planck data 2018.

Automated summary

This paper investigates holographic inflation within the frameworks of f(T) gravity and DGP braneworld model, exploring various inflationary parameters using a modified infrared cutoff. The behavior of these parameters is presented graphically and shown to be consistent with Planck 2018 data.
