Tsallis holographic model of dark energy: Cosmic behavior, statefinder analysis and ωD–ω′D pair in the nonflat universe
Abstract
This paper investigates the Tsallis holographic dark energy (THDE) model in accordance with the apparent horizon as an infrared cut-off, in a non flat universe. The cosmological evolution of the deceleration parameter and equation of state of THDE model are calculated. The evolutionary trajectories are plotted for the THDE model for distinct values of the Tsallis parameter δ besides distinct spatial curvature contributions, in the statefinder (r,s) parameter-pairs and ωD–ω′D plane, considering the present value of dark energy (DE) density parameter ΩD0, ΩD0=0.72, in the light of WMAP+eCMB+BAO+H0 observational data. The statefinder and ωD–ω′D plane plots specify the feature of the THDE and demonstrate the separation between this framework and other models of DE.
