Perturbations in f ( >) cosmology and the spin connection

In this short paper we explain how the spin connection variables should be introduced into the perturbation theory of the spatially flat cosmology in f( ) gravity with the background tetrad eaμ=a(t)ċδaμ and zero background spin connection. In passing, we also correct some small mistakes in our previ...

Summary:In this short paper we explain how the spin connection variables should be introduced into the perturbation theory of the spatially flat cosmology in f( ) gravity with the background tetrad eaμ=a(t)ċδaμ and zero background spin connection. In passing, we also correct some small mistakes in our previous work on this subject.
