Covariant density and velocity perturbations of the quasi-Newtonian cosmological model in $f(T)$ gravity
We investigate classes of shear-free cosmological dust models with irrotational fluid flows within the framework of $f(T)$ gravity. In particular, we use the $1 + 3$ covariant formalism and present the covariant linearised evolution and constraint equations describing such models. We then derive the...
