Spin connection and cosmological perturbations in scalar-torsion gravity

Abstract
In this paper we generalize our previous results on spin connection for the linear scalar cosmological perturbation in theory to wider class of theories which includes a scalar field non-minimally coupled to torsion, and allows -dependence of the function . The case of , with a scalar field non-minimally coupled to torsion needs a special treatment. In both considered cases we derive self-consistent equations of motion for cosmological perturbation using a solution for non-trivial spin connection.
