Abstract

© 2016, Springer Science+Business Media Dordrecht. In a recent work, a particular class of f(T) gravity, where T is the teleparallel torsion scalar, has been derived. This class has been identified by flat-like universe (FLU) assumptions (El Hanafy and Nashed 2015). The model is consistent with the early cosmic inflation epoch. A quintessence potential has been constructed from the FLU f(T) -gravity. We show that the first order potential of the induced quintessence is a quasi inverse power law inflation with an additional constant providing an end of the inflation with no need to an extra mechanism. At e-folds N∗= 55 before the end of the inflation, this type of potential can perform both E and B modes of the cosmic microwave background (CMB) polarization pattern.
