Accelerating Kantowski-Sachs Universe in (, )Gravity

AbstractThe present investigation deals with the (, ) gravity, which was recently attracted attention of many cosmologists. In thistheory, the gravitational action is formulated using an arbitrary function (, ) where represents the non-metricity scalarand denotes the trace of the energy-momentum tensor. In this paper, we have investigated Kantowski-Sachs cosmologicalmodels in the context of (, )gravity under the influence of wet dark fluid. A functional form (, ) = +, where andare constants, is chosen for derivation. We analyze three different models and obtained the exact solution of thefield equations by considering i) special form of deceleration parameter = −1 + ii) hyperbolic scale factor () = sinh() iii) the scale factor () = which generates a time-dependent deceleration parameter. We also studied some physical and kinematical parameters of the investigated models and discussed their behavior graphically.
