Abstract :  This work is devoted to studying the generalized nature of the entropy function in a specific form of the scalar-tensor-vector insert ignore into journalissuearticles values(STeVe); theory of gravity for the Friedmann-Lemaitre-Robertson-Walker insert ignore into journalissuearticles values(FLRW); spacetime in the state of thermal equilibrium. For this purpose, we define an equilibrium picture of thermodynamics by making use of a suitable set of the dark energy density and dark pressure descriptions, which defines an energy-momentum tensor obeying the local energy conservation law. Furthermore, we also discuss our results numerically in order to get additional implications.
