Realistic f(T) model describing the de Sitter epoch of the dark energy dominated universe

S. B. Nassur, A. V. Kpadonou, M. E. Rodrigues +2

We consider an exponential model within the so-called f(T) theory of gravity, where $T$ denotes the torsion scalar. We focus our work on a cosmological feature of such a model, che…
