Quest for the extra degree of freedom in f (T) gravity

It has recently been shown that f(T) gravity has n(n-3)2+1 physical degrees of freedom (d.o.f.) in n dimensions, contrary to previous claims. The simplest physical interpretation of this fact is that the theory possesses a scalar d.o.f. This is the case of f(R) gravity, a theory that can be understo...
