Growth factor in $f(T)$ gravity
186 citations recorded by the source corpus.
We derive the evolution equation of growth factor for the matter over-dense perturbation in f(T) gravity. For instance, we investigate its behavior in power law model at small redshift and compare it to the prediction of Lambda CDM and dark energy with the same equation of state in the framework of Einstein general relativity. We find that the perturbation in f (T) gravity grows slower than that in Einstein general relativity if partial derivative f/partial derivative T > 0 due to the effectively weakened gravity.
