AbstractWe study teleparallel gravitational theories which are invariant under the conformal transformations. The wide family of the gravitational Lagrangians that are invariant under conformal transformations has been investigated. Cosmological solutions inspired by the observational data for a flat Universe in vacuum have been found. There are significant limitations in adding matter fields to the cosmological models by preserving the conformal symmetry. Friedmann-Robertson-Walker (FRW…
