Modified teleparallelism: an alternative approach of modified gravity

CECILIA BEJARANO

Encuentro; Windows on Quantum Gravity: Season 2; 2015

The so-called f(T) theories of gravity are a generalization of the well-known teleparallel equivalent of General Relativity in which the dynamical relevant object is the tetrad instead of the metric tensor and the degrees of freedom are encoded in the torsion rather than in the curvature. I will present the principal features of the teleparallel picture and some examples showing how this novel approach works.
