Evolution of perturbations in the model of Tsallis holographic dark energy

Physics Letters B
We investigated evolution of metric and density perturbations for Tsallis model of holographic dark energy with energy density ∼L2γ−4, where L is length of event horizon or inverse Hubble parameter and γ is parameter of non-additivity close to 1. Because
