COSMOLOGICAL MODELS BASED ON SCALAR-TORSION GRAVITY

Fomin I.V.

Cosmological models based on teleparallel gravity with a non-minimal coupling between the scalar field and torsion (scalar-torsion gravity) are considered in the context of their comparison with the case of Einstein gravity (GR) and the teleparallel equivalent of general relativity (TEGR). A classification of cosmological inflationary models is proposed based on the type of dependence of the tensor-scalar ratio on the spectral index of scalar perturbations. The difference between inflationary models based on scalar-torsion gravity and models based on GR and TEGR is shown in the context of their verification using observational data based on this dependence.
