through noncommutative entropic gravity    [PDF]

In this paper, we analyze the nonextensive Tsallis' statistical mechanics in the light of Verlinde's formalism. As an important result we obtain, with the aid of a noncommutative entropic gravity, a new bound for Tsallis nonextensive parameter that is clearly different from the one present in the current literature. We also derive the Friedmann equations in a nonextensive scenario.
