Observational constraints on growth index with cosmography
Abstract In the literature, it was proposed that the growth index $$\gamma $$ γ is useful to distinguish the scenarios of dark energy and modified gravity. In the present work, we consider the constraints on the growth index $$\gamma $$ γ by using the latest observational data. To be model-independe...
