Lyra cosmologies with the dynamical system perspective
Ashutosh Singh
Abstract:In this study, we revisit the homogeneous and isotropic, spatially curved model in the Lyra geometry framework. We apply the dynamical system approach to study the universe evolution in model. The present cosmic dynamical system formulation is independent of the model parameter which yields the universe expansion phases dominated by the stiff fluid, radiation, dark matter and dark energy. These expansion phases in the Lyra model are consistent with the General relativity model. In addition, the displacement ve… Show more
