Abstract
In this work, we examine a five-dimensional anisotropic Bianchi type III cosmological model within the framework of Lyra geometry. We investigate the matter bounce scenario under the dark energy condition for the equation of state relationship with . Utilizing the energy–momentum tensor of a perfect fluid, we derive the solution for the model universe. Our proposed model also evaluates the behavior of energy conditions, state-finders, the current value of the deceleration parameter and stability conditions.
