Dynamics of single-field inflation in the framework of holographic f(T) gravity

Abstract

In the work reported in the present paper, we have considered the inflationary dynamics inspired by holographic Ricci dark energy (HRDE) with the energy density [Formula: see text] in the framework of [Formula: see text] gravity. We have considered a [Formula: see text]-gravity model in linear form, which is sourced by a canonical scalar field due to the HRDE. We have investigated an inflationary Universe in this framework through slow-roll formalism. We also studied the scalar spectral index [Formula: see text] and tensor-to-scalar ratio [Formula: see text], which have come out to be in agreement with WMAP[Formula: see text]BAO[Formula: see text][Formula: see text] and Planck 2015 data.
