The covariant formulation of <i>f</i> ( <i>T</i> ) gravity

We show that the well-known problem of frame dependence and violation of local Lorentz invariance in the usual formulation of f(T) gravity is a consequence of neglecting the role of spin connection. We re-formulate f(T) gravity starting from, instead of the 'pure tetrad' teleparallel gravity,the cov... View More
