Modified Friedmann equations from Tsallis entropy

It was shown by Tsallis and Cirto that thermodynamical entropy of a gravitational system such as black hole must be generalized to the non-additive entropy, which is given by Sh=γAβ, where A is the horizon area and β is the nonextensive parameter [1]. In this paper, by taking the entropy associated...
