| Abstract: | The thermodynamic viability of some dark energy models reconstructed through the cosmological jerk parameter is investigated. Some models, already available in the literature, are picked up for the purpose. The models are broadly classified in two categories, depending on whether there is an interaction in the dark sector or not. The validity of the Generalized Second law of Thermodynamics (GSL) is used as the diagnostics. Hayward–Kodama temperature is considered in place of Hawking temperature in order to account for the dynamical nature of the spacetime. It is found that depending on the parametrization ansatz for jerk, the total entropy is increasing with time, so it is quite possible to find viable models. This holds even with an interaction in the dark sector. |
