摘要: We investigate modified theories of gravity in the context teleparallel geometries. It is well known that models based on torsion scalar are not invariant under local Lorentz transformations while modifications Ricci are. This motivates study a model depending and divergence vector. derive equivalent $f(R)$ as particular subset these also show this unique theory class transformation. Furthermore one can $f(T)$ admitting second-order field equations.
