| Popis: | The presence of compact extra dimensions in cosmological scenarios in the context of f(T)-like gravities is discussed. For the case of toroidal compactifications, the analysis is performed in an arbitrary number of extra dimensions. Spherical topologies for the extra dimensions are then carefully studied in six and seven spacetime dimensions, where the proper vielbein fields responsible for the parallelization process are found. Comment: 11 pages, one figure (added). Typos corrected, manuscript improved. Additional material is contained in section IV. Accepted for publication in Physical Review D |
