In VEP formalism the off-shell spin connection admits a one-parameter family of conformal transformations interpolating between Nieh-Yan and conformally invariant torsion; dynamically generated torsion lacks well-defined conformal properties and affects fermions and conformal scalars.

abstract
It is shown that the acceleration of the universe can be understood by considering a F(T) gravity models. For these F(T) gravity models, a variant of the accelerating cosmology reconstruction program is developed. Some explicit examples of F(T) are reconstructed from the background FRW expansion history.

Different types of torsion and their effect on the dynamics of fields
In VEP formalism the off-shell spin connection admits a one-parameter family of conformal transformations interpolating between Nieh-Yan and conformally invariant torsion; dynamically generated torsion lacks well-defined conformal properties and affects fermions and conformal scalars.
