Present accelerated expansion of the universe from new Weyl-Integrable gravity approach
We investigate if a recently introduced formulation of general relativity on a Weyl-Integrable geometry, contains cosmological solutions exhibiting acceleration in the present cosmic expansion. We derive the general conditions to have acceleration in the expansion of the universe and obtain a partic...

| Resumo: | We investigate if a recently introduced formulation of general relativity on a Weyl-Integrable geometry, contains cosmological solutions exhibiting acceleration in the present cosmic expansion. We derive the general conditions to have acceleration in the expansion of the universe and obtain a particular solution for the Weyl scalar field describing a cosmological model for the present time in concordance with the data combination Planck + WP + BAO + SN. |
