Some models of holographic dark energy on the Randall-Sundrum brane and observational data

The some models of holographic dark energy for Randall-Sandrum brane are considered. For first class of dark energy models we take energy density in form $\sim L^{2γ-4}$ where $L$ is size of events horizon in Universe and $γ$ is parameter (Tsallis holographic energy). Analysis of observational data allows to define upper limit on value of $δ=ρ_{0}/2λ$ ($ρ_{0}$ is current energy density in the Universe and $λ$ is brane tension). Then we investigate models for which dark energy density has form $ρ_{de}=C^{2}L^{-2}-C_{1}^{2}H^{2}$ where $H$ is Hubble parameter.
