Description
The cosmological perturbations for a multi-component cosmic medium is investigated
in the frame-work of the modified teleparallel gravity. The evolution equations of theperturbations for each component fluid are derived following the covariant and gaugeinvariant perturbations formalism. For the analysis of our results, we consider the power-law $f(T)$ gravity toy model and study the growth of the matter density fluctuations deep in the radiation- and dust-dominated epochs. We will then highlight the effect of torsion in the formation of large-scale structure formation in the universe.
