The reconstructed model is found to exhibit significant sensitivity to the parameter space $(H_0, a_0, n, \\delta, \\zeta,r_d)$ and the initial conditions. The evolution of the equation of state and deceleration parameters is found to be highly dependent "},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"The reconstructed THDE model in
