Large scale structure and matter power spectrum in f ( T ) gravity

In the present manuscript the scalar linear perturbations and matter power spectrum are investigated in the context of f(T) gravity using both dynamical system and 1 + 3 covariant approaches. After introducing the background gravitational field equations in the context of f(T) gravity, we obtain autonomous differential equations using dynamical system analysis. We then define covariant perturbation variables and use scalar decomposition, harmonic and redshift transformation techniques to obtain
