Generalized scalar tensor theory reveals stability and quintessence nature of the Kantowski-Sachs model, indicating essential insights into dark energy dynamics.
By considering generalized scalar tensor theory, as the gravitational theory, we have investigated the dynamical evolution of the homogeneous and anisotropic Kantowski-Sachs space in the presence of Renyi holographic dark energy. To obtain the solution for this model, we have derived the field equations and we have also analyzed the various physical and geometrical parameters of the model, such as deceleration, jerk, EoS, EoS plane, statefinder pair, density, squared speed of sound and the Om-diagnostic. It is shown from these parameters that the model is very much stable, projecting a quintessence nature and also, obtained model depicts the ΛCDM model. Our observations and conclusions from the constructed model are in good agreement with the recent studies.
