摘要：

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.
