Özet

In this work, we have analyzed the cosmology of the Tsallis holographic dark energy (THDE), a particular case of Nojiri-Odintsov HDE proposed in [S. Nojiri and S. D. Odintsov, Gen. Relativ. Gravit. 38 (2006) 1285; Eur. Phys. J. C 77 (2017) 528], using Hubble's horizon cutoff in [Formula presented] model considering pressureless dark matter. We have examined the equation of state (EoS) parameters in this scenario. The deceleration parameter has been evaluated for this interacting model to justify the late-time acceleration of the expanding universe. We have also studied the cosmological consequences of Statefinder pair, [Formula presented] diagnostics, r-q plane and [Formula presented] pair for interacting THDE in [Formula presented] model. We have also illustrated the cosmology of the interacting THDE using Hubble's horizon cutoff in [Formula presented] model. The EoS parameter, deceleration parameter and Statefinder pair are studied in this interacting scenario. Attainment of [Formula presented] fixed point has been observed for both models. We have also constrained model parameters based on observational data sets through the formalism of [Formula presented] minimum test.
