Non-trivial frames for f(T) theories of gravity and beyond

Mostrar todas las versiones(3)

Some conceptual issues concerning f(T) theories - a family of modified gravity theories based on absolute parallelism - are analyzed. Due to the lack of local Lorentz invariance, the autoparallel frames satisfying the field equations are evasive to an a priori physical understanding. We exemplify th...
