摘要
The equivalence between metric and Palatini formalismsin f(R)-gravity can be achieved in the general context of theories with divergence-freecurrent. This equivalence is a necessary result of asymmetry which is included in a particular conservation equation of the current. Infact the conservation equation, by an appropriate redefinition of the introduced auxiliary field, may be encoded in a massless scalar field equation.
